Apple's new account deletion guidelines suggest that apps using Sign In with Apple should use Sing in With Apple REST API to revoke the app's access to the user's Apple Id when the player account is deleted: https://developer.apple.com/support/offering-account-deletion-in-your-app
My app uses Sign in with Apple to provide account creation and authentication to users. What changes are necessary to support users who delete their accounts? Apps that support Sign in with Apple should use the Sign in with Apple REST API to revoke user tokens.
Could you add support for revoking the access so that when a revoke request would be made to PlayFab from the game client it would interact with Sign In with Apple REST API to revoke the access.
