avast tray icon mobile

I have install avast mobile all working fine but tray icon is not visible.

How to enable it permanently?

Hi, we’ve replaced the icon with a permanent notification that you should see in your status bar. The icon is now only visible when there is something that requires your attention.

How do I get rid of this permanent notification, please, thanks

As it is PERMANENT, you don’t.
Only way to get rid of it is removing the tool.

Tools–Settings–Notifications–Permanent notification.
However, we do not recommend this - when the notification is active, the Android cannot kill the app and leave the device unprotected. In other words, as long as the notification is on, your device is protected.
