经过大量搜索后，我没有从Firebase那里得到答案来区分2个应用 所以我只是在后台消息服务中添加了一个条件，知道该应用程序是开发版还是主版本，然后如果它是我的正确版本，则推送通知

after a lot of search i didn't got an answer from firebase side to differentiate between 2 apps so i just made a condition into background message service and know if the app is develop or master version and then push the notification if it's my correct version
