+/**
+ * ## CIAM Provider
+ *
+ * This provider is designed to integrate with a CIAM (Customer Identity and Access Management) service.
+ * It expects a set of endpoints to be configured for OAuth 2.0 authorization, token exchange, and user info retrieval.
+ *
+ * ### Configuration
+ *
+ * To use this provider, you must pass a configuration object with the following properties:
+ *
+ * - `clientId`: The client ID provided by your CIAM service.
+ * - `clientSecret`: The client secret provided by your CIAM service.
+ * - `authorizationUrl`: The authorization endpoint of your CIAM service.
+ * - `tokenUrl`: The token endpoint of your CIAM service.
+ * - `userinfoUrl`: The userinfo endpoint of your CIAM service.
+ * - `issuer`: The issuer URL of your CIAM service.
+ * - `jwksEndpoint`: The JWKS endpoint of your CIAM service.
+ *
+ * Additionally, you can override any of the default `OAuthConfig` properties.
+ *
+ * @param {Omit<OAuthUserConfig<Record<string, any>>, 'checks'> & {
+ *   authorizationUrl: string;
+ *   tokenUrl: string;
+ *   userinfoUrl: string;
+ *   issuer: string;
+ *   jwksEndpoint: string;
+ * }} options
+ * @returns {OAuthConfig<Record<string, any>>}
