How can I automatically suspend my jellyfin server?

I have a jellyfin server running on Ubuntu 22.04.5 LTS x86_64 and I would like to schedule it, so that the server goes into sleep or hibernate 30-60 minutes after the last playback stops. This is to save power and reduce noise because the server is running on an old desktop of mine.

I have some experience in scripting but I am not sure how to get the status of jellyfin for running playbacks
