confirm registration with deep link (IOS)

## Issue

Hey everyone, I have implemented auth flow with react native app auth + keyclock and faced issue. My registration flow consist of two steps:
1) I press sign up button, call authorize, is opened additional window with form, I fill data and get link on email that I have to press in order to confirm registration
2) I press link (deep link to my application with params like code, state ...) on email and I will be redirected to app

Seems that AppAuth-Ios does not handle deep link with params from email to app and in order to get access_token I have to log in with `authorize`
hope I explained clear
