/**
 * A fully featured wallet connection component that allows to:
 *
 * - Connect to 500+ external wallets
 * - Connect with email, phone, passkey or socials
 * - Convert any wallet to a ERC4337 smart wallet for gasless transactions
 * - Sign in with ethereum (Auth)
 *
 * Once connected, the component allows to:
 *
 * - Resolve ENS names and avatars
 * - Manage multiple connected wallets
 * - Send and receive native tokens and ERC20 tokens
 * - View ERC20 tokens and NFTs
 * - Onramp, bridge and swap tokens
 * - Switch chains
 * - Connect to another app with WalletConnect
 *
 * @example
 *
 * ## Default setup
 *
 * ```tsx
 * import { createThirdwebClient } from "thirdweb";
 * import { ConnectButton } from "thirdweb/react";
 *
 * const client = createThirdwebClient({ clientId: "YOUR_CLIENT_ID" });
 *
 * <ConnectButton
 *    client={client}
 * />
 * ```
 *
 * [View all available config options](https://portal.thirdweb.com/references/typescript/v5/ConnectButtonProps)
 *
 * ## Customization options
 *
 * ### Customizing wallet options
 *
 * ```tsx
 * <ConnectButton
 *    client={client}
 *    wallets={[
 *      createWallet("io.metamask"),
 *      createWallet("com.coinbase.wallet"),
 *      createWallet("me.rainbow"),
 *    ]}
 * />
 * ```
 *
 * [View all available wallets](https://portal.thirdweb.com/typescript/v5/supported-wallets)
 *
 * ### Customizing the default chain to connect to
 *
 * ```tsx
 * import { sepolia } from "thirdweb/chains";
 *
 * <ConnectButton
 *   client={client}
 *   chain={sepolia}
 * />
 * ```
 *
 * ### Enabling Account Abstraction
 *
 * By passing the `accountAbstraction` prop, ALL connected wallets will be converted to smart accounts.
 * And by setting `sponsorGas` to `true`, all transactions done with those smart accounts will be sponsored.
 *
 * ```tsx
 * <ConnectButton
 * client={client}
 * accountAbstraction={{
 *   chain: sepolia,
 *   sponsorGas: true,
 * }}
 * />;
 * ```
 *
 * Note that this prop doesn't affect ecosystem wallets. Ecosystem wallets will only be converted to smart accounts if the ecosystem owner has enabled account abstraction.
 *
 * ### Enabling sign in with ethereum (Auth)
 *
 * ```tsx
 * <ConnectButton
 * client={client}
 * auth={{
 *   isLoggedIn: async (address) => {
 *     console.log("checking if logged in!", { address });
 *     return await isLoggedIn();
 *   },
 *   doLogin: async (params) => {
 *     console.log("logging in!");
 *     await login(params);
 *   },
 *   getLoginPayload: async ({ address }) =>
 *     generatePayload({ address }),
 *   doLogout: async () => {
 *     console.log("logging out!");
 *     await logout();
 *   },
 * }}
 * />;
 * ```
 *
 * ### Customizing the theme
 *
 * ```tsx
 * <ConnectButton
 *    client={client}
 *    theme="light"
 * />
 * ```
 *
 * For more granular control, you can also pass a custom theme object:
 *
 * ```tsx
 * <ConnectButton
 *    client={client}
 *    theme={lightTheme({
 *      colors: {
 *        modalBg: "red",
 *      },
 *    })}
 * />
 * ```
 *
 * [View all available themes properties](https://portal.thirdweb.com/references/typescript/v5/Theme)
 *
 * ### Overriding styles using class names
 *
 * Some elements in this component have classes with a `tw-` prefix.
 * You can target these classes in your own CSS stylesheet to override their styles.
 *
 * In some cases, you may need to use the `!important` flag for the override to take effect. Do not use on auto-generated class names, as they may change between builds.
 *
 * ```css
 * .tw-back-button {
 *   background-color: red !important;
 * }
 * ```
 *
 * ### Changing the display language
 *
 * ```tsx
 * <ConnectEmbed
 *    client={client}
 *    locale="ja_JP"
 * />
 * ```
 *
 * [View all available locales](https://portal.thirdweb.com/references/typescript/v5/LocaleId)
 *
 * ### Customizing the connect button UI
 *
 * ```tsx
 * <ConnectButton
 *    client={client}
 *    connectButton={{
 *      label: "Sign in to MyApp",
 *    }}
 * />
 * ```
 *
 * ### Customizing the modal UI
 *
 * ```tsx
 * <ConnectButton
 *    client={client}
 *    connectModal={{
 *      title: "Sign in to MyApp",
 *      titleIcon: "https://example.com/logo.png",
 *      size: "compact",
 *    }}
 * />
 * ```
 *
 * ### Customizing details button UI (after connecting)
 *
 * ```tsx
 * <ConnectButton
 *    client={client}
 *    detailsButton={{
 *      displayBalanceToken: {
 *        [sepolia.id]: "0x...", // token address to display balance for
 *        [ethereum.id]: "0x...", // token address to display balance for
 *      },
 *    }}
 * />
 * ```
 *
 * [View all available auth helper functions](https://portal.thirdweb.com/references/typescript/v5/createAuth)
 *
 * ### Customizing the Auth sign in button (after connecting, but before authenticating)
 *
 * ```tsx
 * <ConnectButton
 *   client={client}
 *   auth={{ ... }}
 *   signInButton: {
 *     label: "Authenticate with MyApp",
 *   },
 * }}
 * />;
 * ```
 *
 * ### Customizing supported Tokens and NFTs
 *
 * These tokens and NFTs will be shown in the modal when the user clicks "View Assets", as well as the send token screen.
 *
 * ```tsx
 * <ConnectButton
 *   client={client}
 *   supportedTokens={{
 *     [ethereum.id]: [
 *       {
 *         address: "0x...",
 *         name: "MyToken",
 *         symbol: "MT",
 *         icon: "https://example.com/icon.png",
 *       },
 *     ],
 *   }}
 *   supportedNFTs={{
 *     [ethereum.id]: [
 *       "0x...", // nft contract address
 *     ],
 *   }}
 * />
 * ```
 *
 * ### Customizing the orders of the tabs in the [View Funds] screen
 * When you click on "View Assets", by default the "Tokens" tab is shown first.
 * If you want to show the "NFTs" tab first, change the order of the asset tabs to: ["nft", "token"]
 * Note: If an empty array is passed, the [View Funds] button will be hidden
 *
 * ```tsx
 * <ConnectButton
 *   client={client}
 *   detailsModal={{
 *     assetTabs: ["nft", "token"],
 *   }}
 * />
 * ```
 *
 * ### Callback for when the details modal is closed
 * ```tsx
 * <ConnectButton
 *   detailsModal={{
 *     onClose: (screen: string) => {
 *       console.log({ screen });
 *     }
 *   }}
 * />
 * ```
 *
 * @param props
 * Props for the `ConnectButton` component

 * Refer to [ConnectButtonProps](https://portal.thirdweb.com/references/typescript/v5/ConnectButtonProps) to see the available props.
 *
 * @returns A JSX element that renders the <ConnectButton> component.
