OptionalredirectOverrides OidcConfig.redirectUri for the session check request.
OptionalresponseThe response type for the session check. Default: SessionCheckResponseType.None
OptionalscopeOAuth scope. Default: 'openid'.
OptionalsubjectIf provided, the sub claim in the returned id_token must match. id_token mode only.
Both modes send id_token_hint if a stored token is available; the AS falls back to the browser session cookie if it is absent. This means a session check can succeed even without stored tokens.
