Cognito make username an email google auth

Question

How do I make my cognito user pool username an email with google identity provider.

It is very confusing as well. In attribute mappings it says that google sub is username, but username has a format of "Google_randomnumber"

Please help me how do I assign my own username when doing google auth with cognito user pools?

This is what looks like when you click the User in Users and Groups:
