/**
 * <p>Creates an encrypted token that is used by a chat participant to establish an individual
 *          WebSocket chat connection to a room. When the token is used to connect to chat, the
 *          connection is valid for the session duration specified in the request. The token becomes
 *          invalid at the token-expiration timestamp included in the response.</p>
 *          <p>Use the <code>capabilities</code> field to permit an end user to send messages or
 *          moderate a room.</p>
 *          <p>The <code>attributes</code> field securely attaches structured data to the chat session; the data is
 *          included within each message sent by the end user and received by other participants in the
 *          room. Common use cases for attributes include passing end-user profile data like an icon,
 *          display name, colors, badges, and other display features.</p>
 *          <p>Encryption keys are owned by Amazon IVS Chat and never used directly by your
 *          application.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { IvschatClient, CreateChatTokenCommand } from "@aws-sdk/client-ivschat"; // ES Modules import
 * // const { IvschatClient, CreateChatTokenCommand } = require("@aws-sdk/client-ivschat"); // CommonJS import
 * // import type { IvschatClientConfig } from "@aws-sdk/client-ivschat";
 * const config = {}; // type is IvschatClientConfig
 * const client = new IvschatClient(config);
 * const input = { // CreateChatTokenRequest
 *   roomIdentifier: "STRING_VALUE", // required
 *   userId: "STRING_VALUE", // required
 *   capabilities: [ // ChatTokenCapabilities
 *     "STRING_VALUE",
 *   ],
 *   sessionDurationInMinutes: Number("int"),
 *   attributes: { // ChatTokenAttributes
 *     "<keys>": "STRING_VALUE",
 *   },
 * };
 * const command = new CreateChatTokenCommand(input);
 * const response = await client.send(command);
 * // { // CreateChatTokenResponse
