Yes, the user has to be logged in for row level security to apply at the user level.  Take a look at this article on dynamic rls.

Hi. Your question is not quite clear but let me try. Yes they have to login.

In order to use RLS in a report, all the users accessing to this report must have a pro account (or premium capacity and any account). When the login in the platform with their own professional account, the USERNAME() will resolve finding the email.
