c# – Unity: Methods to distinguish a participant signed in anonymously from a participant signed in with Apple Signal In

I work on a Unity IOS sport, and I’ve applied a Leaderboard. When the Leaderboard scene hundreds, the participant is robotically signed in anonymously :

And it really works completely, the scores are displayed correctly on the display screen.

However then, if the participant needs to add his personal finest rating, he must be related (with AppleId). My query is easy: the right way to correctly distinguish a nameless participant from a participant already related with apple ? (So I can stop the add of the rating for nameless gamers)

I attempted to test if “AuthenticationService.Occasion.PlayerInfo.GetAppleId()” was returning one thing, nevertheless it by no means returns something. I requested Copilot and it instructed me that playerId of Nameless gamers begins with “nameless”, nevertheless it’s not true.

Thanks upfront for serving to me
