DVR Server on Mac Mini, Using Synology NAS Share?

I currently run Channels DVR Server on Windows 11 Pro, with recordings going to and stored on a NAS share from my Synology.

I really hate Windows 11 and am trying to recreate my Channels DVR server on a new M4 Mac Mini, but I can't find the NAS on the "Where do you want to store your data and recordings?" screen. In fact I can't seem to access anything on the network outside of the Mac Mini itself. There's probably some simple setting I'm missing, but could someone please point me to it? Thanks!

@chDVRuser You probably have the most recent experience with this.

I gave up trying to use my Mac Mini for seven DVR servers and still have them running in containers on my Synology.
