Autostart without login?

Im currently running Jellyfin on a linux mint machine and to make it real nice I’m new to both.

I wanted to have jellyfin start automatically when the pc boots up without having to do anything.

So I set it to start automatically via the startupprograms manager as I have the flatpack installed.

Problem is I still need to enter my login password on Linux before the server starts.

Isn’t there a way to have jellyfin running before login?
