Remote access to lan works, maybe some of the other options too.
The trick is to allow access from the wireguard network to your delugevpn docker (I’m assuming you’re using binhex’s delugevpn). Add the wireguard network range to the LAN_Network variable of the vpn docker, comma separated from your normal lan range. If you are using the default wireguard settings the range to add is: 10.253.0.0/24
