The SiwA sheet is presented in unexpected places from a bincompat app using web authentication. This is due to an incorrect bundle identifier, but the preferred method is specifying a scene identifier to anchor to. AuthKit has made changes to accept a callerSceneIndetifier from the auth request (ASAuthorizationProviderExtensionAuthorizationRequest). So we need to return the correct sceneID. WebKit (in SOAuthorizationSession) is responsible for firing off the request, which is actually an SOAuthorizationRequest. Later, AuthKit wraps this request in the AS..AuthorizationRequest.
