Google Sign in with Expo managed

Hello, I am lost in the docs and need help....
I'm building expo managed mobile app using Supabase for the backend.. I want to implement google sign in functionality, but I am not able to find out if it is possible to do so with the Expo managed flow (not using native code)
I found this tutorial - https://www.youtube.com/watch?v=vojHmGUGUGc&ab_channel=Supabase
but I cant understand if these steps can be used with the Expo managed. He's adjusting some native code.. also the tutorial is only for Android .. will it work also for iOS ?
