How can I set notification sound when app is not r

Question

I'm trying to make notification ringing when app is not running in IOS.

Here is my code.

  this.notificationListener = firebase.notifications().onNotification((notification: Notification) => {

    // SET SYSTEM DEFAULT SOUND!
    notification.setSound("default");
    firebase.notifications().displayNotification(notification);

  });

When app is in background or foreground ( Maybe I can say 'app is running'), notification rings well.

Should I need to use other listener? Or should I need to add my own sound file for ringing?

Finally, I know how to do this. This issue was not related to react-native-firebase, it was related to my server.

When server post message to app, server can set several options like sound, badge.

If you set sound section to 'default', you can get default notification sound when notification is coming even if your app is on background.

I hope my answer can help react-native-firebase beginners like me.
