I tried it and it works well.
Steps:
Install Ubuntu Server 24.04.02 and then:
sudo snap install ubuntu-frame
sudo snap set ubuntu-frame daemon=true
sudo snap install chromium
sudo snap set chromium url=https://clyderiveratlas.ca
sudo snap set chromium daemon=true
snap connect chromium:wayland
To change the URL:
sudo snap set chromium url=https://discourse.ubuntu.com/t/current-guide-for-a-firefox-based-kiosk-using-ubuntu-frame/57638
sudo snap restart chromium
I am happy to see that the configuration persists and the ubuntu-frame and chromium snaps come up again after a reboot.
