How can I disable "app is running in the background" notifications? I've a notification from Android system that I can only snooze, not remove permanently, about an app running in the background. It's specifically about Keepass2Android:


  Keepass2Android is running in the background


I know it's running in the background so I don't need to be reminded about it constantly. Most annoying is that it takes up unnecessary space.

Is there a way to disable this notification?
I am on Oreo 8.0.0 and couldn't find a setting for this so ended up using this Hide  "running in the background" Notification

I have several apps running in background and disabled them all using this app, as it serves no useful purpose for me to know

Auto Notification is another app that has this feature amongst other Tasker oriented features if you are interested. 

I preferred the first one since I don't use Tasker

Edit: These are Bye the way notifications
