/**
 * Add Slack login to your page.
 *
 * ### Setup
 *
 * #### Callback URL
 * ```
 * https://example.com/api/auth/callback/slack
 * ```
 *
 * #### Configuration
 *```ts
 * import { Auth } from "@auth/core"
 * import Slack from "@auth/core/providers/slack"
 *
 * const request = new Request(origin)
 * const response = await Auth(request, {
 *   providers: [
 *     Slack({ clientId: SLACK_CLIENT_ID, clientSecret: SLACK_CLIENT_SECRET }),
 *   ],
 * })
 * ```
 *
 * ### Resources
 *
 * - [Slack Authentication documentation](https://api.slack.com/authentication)
 * - [Sign-in with Slack](https://api.slack.com/docs/sign-in-with-slack)
 * - [Slack app console](https://api.slack.com/apps)
 *
 * ### Notes
 *
 * By default, Auth.js assumes that the Slack provider is
 * based on the [Open ID Connect](https://openid.net/specs/openid-connect-core-1_0.html) specification.
 *
 * :::danger
 *
 * Slack requires that the redirect URL of your app uses https, even for local development.
 * An easy workaround for this is using a service like [ngrok](https://ngrok.com/) that creates a secure tunnel to your app, using https. Remember to set the url as `NEXTAUTH_URL` as well.
 *
 * :::
 *
 * :::tip
 *
 * The Slack provider comes with a [default configuration](https://github.com/nextauthjs/next-auth/blob/main/packages/core/src/providers/slack.ts).
 * To override the defaults for your use case, check out [customizing a built-in OAuth provider](https://authjs.dev/guides/configuring-oauth-providers).
 *
 * :::
 *
 * :::info **Disclaimer**
 *
 * If you think you found a bug in the default configuration, you can [open an issue](https://authjs.dev/new/provider-issue).
 *
 * Auth.js strictly adheres to the specification and it cannot take responsibility for any deviation from
 * the spec by the provider. You can open an issue, but if the problem is non-compliance with the spec,
 * we might not pursue a resolution. You can ask for more help in [Discussions](https://authjs.dev/new/github-discussions).
