Email address as identifer, and App privacy details

Hello

I have a question regarding App Privacy Details, concerning the “User ID” field.

On one of my apps, I use email address as identifier during user authentication.

In “App privacy” page (as well in my privacy manifest), I did add “Email Address” as collected data type, and specified that it’s linked to the user.

My question is: Should I add “User ID” to my “App privacy details”, since the email address is used as identifier for the user account?

Thanks in advance
