Sign in with Apple: Differentiate multiple email addresses associated with Apple ID

Hey there,


I would like to open a discussion around handing the case of multiple email addresses inside one Apple ID. For example, I have two email addresses in my demo Apple ID + the anonymous one that goes through the Apple relay services.


Once I select a different email address than my primary one and authenticate, the profile will still include the primary email instead the actually selected one, which makes it kind of hard to distinguish between different email addresses.


The problem is that it seems like they still work with the same "stable" `user` identifier, so I'm asking whats the best practice for handling multiple email addresses.
