Installing NixOS on Framework

Has anyone tried or upgraded to the newer version of NixOS on their Framework? I heard the latest release makes the process of installing a bit easier

I had no issues installing 21.11 on my framework with the 5.15.* kernel. What advantages does 22.05 introduce?

I believe I read somewhere in the release notes about a GUI installer being available or at least a better version of it. Plus an assortment of other improvements.
