Support for a Wayland server in a personalized template?

Based on a msg from ‘todox’ I tried to ~build~ a ‘litterbox’ container.

As the main-developer of ‘Litterbox’ confirmed in a discussion on the project repo, a running Wayland server is a pre-requisite.

Here comes a hopefully simple question: Is this available / supported in Qubes OS R4.3 ?

If yes, please provide some links on what to install exactly - or - where to start reading !

I’d expect it would be possible, but without GUI integration, that is, the VM would display like a “normal” VM (think virt-manager or virtualbox).
