User Profile

We are implementing sign in with Apple(SiwA) for our iOS app. for the signup we require the user's Apple id and email address. We are getting user name and email details everytime when User selects "Show My Email". When User selects "Hide My Email" the very first time only private relay email(unique email address) i am recieving. Second time for that user i am not recieving any email address in the appleIdCredentials object.Some people from different forums suggested to decode the userIdentifier for the email address. Will it be good to decode it or any other way to handle it. Please suggest solution for handleing "Hide My Email" case.Note : My Project is in Objective C.Any help would be appreciated.Thanks in Advance.
