Gnome Remote Desktop

I’d like to be able to enable the remote desktop built into Gnome, I don’t think this is possible in Nix? However I’d like to be wrong.

However I’ve enabled it manually and can see the service running using ss -l. I have also disabled the firewall. Is there another reason why I might not be able to connect to it? I’m having no luck at all with this.

Or is there another way to connect to a logged in session via RDP?
