Haha. No, I’m asking how you installed as there are now different paths to get there (Ubuntu Snap, Docker or the developer’s installation you chose) and I can give you the best help if I understand which of those methods you used.
What is missing in your case are the icons. Let me try to go through that guide and see if I can think of anything that would cause the icons to not appear.
Actually, if you run the Ubuntu Snap (which also should run on Debian), it should pretty much be able to administrate itself, including update to the newest version whenever there is a new release. Is there any particular reason why you choose not to use the Snap?
