Navidrome on my Pi, music on my NAS

I'm curious if there's a specific way to go about doing this?

Can I just set my docker-compose.yaml to

    
volumes:
      - "/opt/navidrome/data:/data"
      - "http://192.168.0.88/Shared Music/:/music:ro"

  

Or do I have to mount the directory first

Or can I use the ND_BASEURL?
