Get custom attributes when calling Auth.currentAuthenticatedUser

I can't seem to find where you would add to the list of attributes returning when requesting logged in user info, I am using an amplify react app and created it with the amplify studio. There is nothing about attribute management in the studio, and I already have the attributes correctly set for read and write permissions. I haven't been able to find any documentation that help specifically with getting the custom attributes I need returned. any help would be great!

The only entry point named is Auth.currentAuthenticatedUser in an Amplify React app; start by locating its authentication documentation and the returned user attributes behavior. Done means the documentation explains how custom attributes are configured or requested and shows how a user can verify they are returned.
