 * ### Setup
 *
 * #### Callback URL
 * ```
 * https://example.com/api/auth/callback/descope
 * ```
 *
 * #### Configuration
 * ```ts
 * import { Auth } from "@auth/core"
 * import Descope from "@auth/core/providers/descope"
 *
 * const request = new Request(origin)
 * const response = await Auth(request, {
 *   providers: [
 *     Descope({
 *       clientId: DESCOPE_ID,
 *       clientSecret: DESCOPE_SECRET,
 *     }),
 *   ],
 * })
 * ```
 *
 * ### Configuring Descope
 *
 * Follow these steps:
 *
 * 1. Log into the [Descope console](https://app.descope.com)
 * 2. Follow the [OIDC instructions](https://docs.descope.com/customize/auth/oidc)
 *
 * Then, create a `.env.local` file in the project root add the following entries:
 *
 * Get the following from the Descope's console:
 * ```
 * DESCOPE_ID="<Descope Issuer's last url segment>" # Descope's Issuer can be found in "Authentication Methods > SSO > Identity Provider" (Can also be taken from "Project > Project ID")
 * DESCOPE_SECRET="<Descope Access Key>" # Manage > Access Keys
 * ```
 *
 * ### Resources
 *
 * - [Descope OIDC](https://docs.descope.com/customize/auth/oidc)
 * - [Descope Flows](https://docs.descope.com/customize/flows)
 *
 * ### Notes
 *
 * The Descope provider comes with a [default configuration](https://github.com/nextauthjs/next-auth/blob/main/packages/core/src/providers/descope.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
 * By default, Auth.js assumes that the Descope provider is based on the [OIDC](https://openid.net/specs/openid-connect-core-1_0.html) spec
 * :::
 *
 * ## Help
 *
 * 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).
