Answer 1

If you want to use your custom Notification when app destroyed.
Make sure your firebase data have format like

{
   ... 
   "data":{
     "title":"New Notification",
     "body":"Test 123"
   },
   ...
}

instead of

{
   ...
   "notification":{
     "title":"New Notification",
     "body":"Test 123"
   },
   ...
} (if you use this way, phone will display DEFAULT Notification instead of YOUR CUSTOM NOTIFICATION when your app destroyed)
