[X2Go-User] How can I connect and view the Display Manager

I'm trying to log in and view the Display Manager login screen. I'm using SDDM as Display Manager, but I can use any kind of Display Manager, like gdm, to get this working.

If I first log in, then I can connect using "Connection to local desktop"

, but I want to view the login screen.

Should this be possible with X2Go. I can't really find any documentation on this. It sort of bypasses the Display Manager.

I'm on Xorg-1.20.14 on NixOS 22.11
