Activate remote desktop using script

I’m trying to make remote desktop sharing easier to access for a user that require frequent screen sharing assistance.

Remote desktop sharing accessible vie Menu->Settings->Sharing->Remote desktop digging is simply too difficult.

I tried to activate the desktop sharing by manually starting systemctl start --user gnome-remote-desktop, but I can’t connect.

I suspect there is ome dbus ceremonial to start it, but I’m not sure about it.

How can I activate/deactivate desktop sharing from a shell script?
