How to prohibit downloading private files from the server?

Question

Django

How to hide files from downloading? For example, I have a video that is available only to a group of users, but if someone sends a link to this video, then prohibit it from downloading and see how to implement it correctly? Please tell me which direction to look.

I looked at the ban through nginx, but as I understand it, it will become unavailable even for display on the site itself

location ^~ /files/score/ {
deny all;
return 404;
}
