Its not that you're "doing it wrong". Just that this isn't an intended use case for Jellyfin. It was intended to be a "home" media server. Everyone has access to everything. You can do some symlink tricks for things like a kid's "curated library" kind thing. But Jellyfin isn't not intended as a dynamic, automated "service" like Netflix or Hulu and there is no intention, afaik, that move in that direction.
