Raspberry pi snap?

I tried installing jami as a snap on raspberry pi (raspbian) with

sudo snap install --edge jami

That gave me jami (edge) 20201027.1.3883929 from Savoir-faire Linux (sfljami) installed – older than the debian packaged version, which surprised me (getting new versions of things with tricky dependencies seems the main draw of snap to me). I also wasn’t able to run it:

snap run jami

You need to connect this snap to the gnome platform snap.

You can do this with those commands:
snap install gnome-3-28-1804
snap connect jami:gnome-3-28-1804 gnome-3-28-1804

I ran those commands successfully, but snap run jami still results in the same message above.

Has anybody had better luck? What did you do?
