The code for the sample application is no longer available in the Apple Developer app. **How to get it? **

We’re using ASWebAuthenticationSession with Universal Link for the redirectURI. On success sign-in, server returns an universal link with the authentication code.    The SceneDelegate, func scene( scene: UIScene, continue userActivity:) is called, but the completionHandler from the WebAuthentication Session is never called and the sign-in screen never dismiss.   Do you have an idea why? Do you have a sample Xcode project?

Is it possible to use a Universal Link with the parameter callbackURLScheme? https://developer.apple.com/documentation/authenticationservices/aswebauthenticationsession/2990952-init

How to call ASWebAuthenticationSession completionHandler from the method scene(_ scene: UIScene, continue userActivity: NSUserActivity) from the SceneDelegate class?
