You are right. The package was not installed. Now it works.
I've installed Ubuntu 22.04 Desktop, minimal. Maybe the package xdg-desktop-portal-gnome is missing for that mode, but should be installed by default.
I apologize for the comment about snap.
This fixes also a problem with google chrome. Chrome freezes after closing a file dialog without that package installed.
I'm very happy with the quick help. Thank you very much.
