I've installed Gnome Shell Extension using Ubuntu 20.04. I was then able to install the Clipboard Indicator extension which then showed up on the top right of the screen (Systray?). I installed the GSConnect extension but it did not have an icon showing in the Systray. I've no idea how to run it. GSConnect is not showing as a process in Systems Monitor. I've put an appropriate comment issue on the extension's web page, but there's no reply. BTW KDE Connect app on my Android phone doesn't see any device: it should see the Ubuntu box if GSConnect was running Ok. Any ideas on how to make GSConnect run?

To see the icon of GSConnect in the tray, you may need to install the extension AppIndicator/KStatusNotifier
