I found this page which shows how a 23.04 server can easily be turned into a "desktop" version. I just tried it on Windows Server 2019 HyperV, and I can confirm that it is working.
Code:
sudo apt -y install ubuntu-desktop
sudo apt -y install gnome-panel gnome-settings-daemon metacity nautilus gnome-terminal
I say "desktop" as it's not 100% identical to the real desktop version - but at least it's running.
