How to remove KDE Connect app icon from Notification bar? I have the KDE Connect app in order to connect my Android phone (Moto Z2 Play) to my Ubuntu machine. With the upgrade to Android 8, this app has a new annoying behavior in that its icon is always in the Notification bar even when not connected. (If I pull down it says "Not connected to any device").   

How can I get the icon to not appear in the Notification bar when the phone is not connected to anything?
Excerpt taken from KDE Connect – New stuff 0x3:

Android Oreo introduced some restrictions in regard to apps running in the background. In the future in order to be able to run in the background KDE Connect needs to show a persistent notification.
To hide the notification you need to long-press it and switch it off. Other notifications from KDE Connect are unaffected by this.
