I'm running Ubuntu 18.04 Bionic Beaver. I've installed the KDE Connect application. (FWIW I do not have KDE Connect Indicator installed as the application seems to be working okay without it.) But it gives me an annoying little phone icon in the system tray (top-right corner of the screen) which I can't seem to get rid of - if I right-click on it, the only option is "Configure" but that menu isn't helpful. How can I hide this icon?
Here's a screenshot of my system tray with the offending icon highlighted in red:
As pomsky suggested in a comment, the "Icon Hider" Gnome extension does the trick.
