Udisks2 or another disk manager for Ubuntu Core

Hi,
I’ve recently started playing with Ubuntu Core on a RPi 4 by trying to get a Plex Server going. No problem getting Plex Server working except that I cannot mount the local disk or a network drive on my NAS.

The documentation says that udisks2 should be available but I read somewhere that it was deprecated and it has been removed from the Snap store.

Is there another way to manage the disks and get them mounted so that I can configure Plex to actually play videos?
