Yes, just opening the Sharing panel with gnome-control-center 1:41.4-1ubuntu12 is enough to attempt to start the RDP service.
systemctl --user status gnome-remote-desktop reports this error:
RDP TLS certificate and key not configured properly
I didn't check open ports but it makes sense that it would open the RDP port even though the RDP service isn't completely working.
