Library Realtime Monitoring not working

[Cap_ca]

I was annoyed by this problem but also did not want to connect my sonarr and jellyfin instance directly. So I implemented a workaround using a script that is run by sonarr (or any other application) whenever new media is added to the library, this script creates a file which is picked up by another application which then triggers a library update via the Jellyfin API.

More info on how and why I did this in the repo:

However this is probably only a solution if you are quite comfortable with Docker and shell scripts.
