Register to firebase notifications before app is launched

Question

I manage to register a firebase notification topic with this code:

 FirebaseMessaging.getInstance().subscribeToTopic("news");

But I want to register this topic after the installation,so even if the application never got launched it would receive the notification. How can I run this line or define it with the installation?

Before you launch the app for the first time no broadcast will arrive to it. It is essentially disabled. Broadcasts such as install referrer come directly after first launch. User has to launch app manually first.
