User Profile

During a successful first time Apple Sign in, we get an `access_token` field back that has data in it (in addition to a refresh_token, and expires_at). I know that to validate a sign in we use the refresh_token, but I was wondering what to do with the access_token we get back? Do we need it for anything?The apple documention on it says(Reserved for future use) A token used to access allowed data. Currently, no data set has been defined for access.So can we ignore it for now?

So in the scenario where a user uses Apple Sign in to sign into my app ... we know it lets them edit their name and choose their Apple email or a relay. My question is ... after creating the user in our system and signing them in, say they don't sign in for a while so their login expires in our system, so they now see the "Apple Signin" again, so they have to login using that ... do they have to go through the same flow of picking their email and name again? or will Apple know what they had before and just present those to the user?
