[Tanu Jain]

Hello team ,I am Tanu ,a beginner in firebase ,I have set up firebase auth in my flutterflow app,the sign up sends the email verification link successfully but that link directs to a very simple confirmation page "Your email verification is successful" . What I want it is that link should direct to the confirmation page I designed.

How to customize URL like mebtioned above.
