PowerBi RLS Row Level Security whole file security

This video is about getting the whole PBIX file restricted but once the people are in they can see all contents.
So HOW do I get my Symantic Model to stop saying security is on the desk top version. Look at this video.
This is about RLS - Row Level Security restricting the whole file to people in an Email only. Hope this helps.

I know it's a bit on the fragmented side but once you see what happens after publishing it's much better.
