Plex Library Folder - Can I just use a UNC Path?

What is the best way to add my NAS UNC folders into the Plex library?
Do I need to mount some sort of drive or can I just type in the UNC path?

For now I have managed to figure out how to mount a UNC path and now I can see it in the Plex library manager.

Probably you like to share how you managed this. Might be interesting for other users as well :wink:
