How to unhide to bar notification on Android 13 ?
 

I've some questions about the setting on the top notification bar on the Nokia XR20 running on Android 13.


I find that it does not show the sound profile on the top bar, so that I can not easily see the phone is on silent mode and missed some calls, how do I change that so I can see all notifications ? beside, in some occasion I see a green dot on the far right of the top bar, but it disappeared in seconds, what was that ?
