push bildirimi nasıl uygulamamıza ekleriz uygulamanın içinde görünmeyecek şekilde ve bunu bilgisayarımızdan nasıl göndeririz
Did you search the forum? Here, I did it for you https://community.appinventor.mit.edu/search?q=push%20notification
Please read through the discussions and you might find a suggestion. You might also explain in more detail how you expect this to work. App Inventor 2 does not have native push notifications. You have to use an extension.
