 1. For the configuration above, change the values for the provider to match your OpenID Connect client setup. Use the following as a guide:
-    - `<your_oidc_label>` is the label that will be displayed on the login page.
-    - `<your_oidc_url>` (optional) is the URL that points to the OpenID Connect provider. For example, `https://example.com/auth/realms/your-realm`.
-      If this value is not provided, the URL is constructed from the `client_options` in the following format: `<client_options.scheme>://<client_options.host>:<client_options.port>`.
-    - If `discovery` is set to `true`, the OpenID Connect provider will try to auto discover the client options using `<your_oidc_url>/.well-known/openid-configuration`. Defaults to `false`.
-    - `client_auth_method` (optional) specifies the method used for authenticating the client with the OpenID Connect provider.
-      - Supported values are:
-        - `basic` - HTTP Basic Authentication
-        - `jwt_bearer` - JWT based authentication (private key and client secret signing)
-        - `mtls` - Mutual TLS or X.509 certificate validation
-        - Any other value will POST the client id and secret in the request body
-      - If not specified, defaults to `basic`.
-    - `<uid_field>` (optional) is the field name from the `user_info` details that will be used as `uid` value. For example, `preferred_username`.
-      If this value is not provided or the field with the configured value is missing from the `user_info` details, the `uid` will use the `sub` field.
-    - `client_options` are the OpenID Connect client-specific options. Specifically:
-
-      - `identifier` is the client identifier as configured in the OpenID Connect service provider.
-      - `secret` is the client secret as configured in the OpenID Connect service provider.
-      - `redirect_uri` is the GitLab URL to redirect the user to after successful login. For example, `http://example.com/users/auth/openid_connect/callback`.
-      - `end_session_endpoint` (optional) is the URL to the endpoint that end the session (logout). Can be provided if auto-discovery disabled or unsuccessful.
-
-      The following `client_options` are optional unless auto-discovery is disabled or unsuccessful:
-
-        - `authorization_endpoint` is the URL to the endpoint that authorizes the end user.
-        - `token_endpoint` is the URL to the endpoint that provides Access Token.
