Describe the solution you'd like
Use the new init method: https://developer.apple.com/documentation/authenticationservices/aswebauthenticationsession/4316247-initwithurl?language=objc
At first glance, this would finally allow us to support universal links better as the callback has better support for detecting callback URLs and schemes: https://developer.apple.com/documentation/authenticationservices/aswebauthenticationsessioncallback?language=objc
