Can I get push notifications with React Native when app is closed?

Question

I'm trying to get notifications and update launcher icon badge on IOS with React-Native/RNFirebase when app is closed. But unfortunately it seems RNFirebase doesn't have any support for it. onNotification() listener doesn't seem working when app is closed. (background modes/push notifications are enabled on XCode)

Is there any workaround for that to update launcher icon badge when notification received and app is closed?

If your app is closed, you can check if it was opened by a notification using: firebase.notifications().getInitialNotification()

here is a sample using it:

const notificationOpen = await firebase
      .notifications()
      .getInitialNotification();
    if (notificationOpen && notificationOpen.notification) {
      let { title, body, data } = notificationOpen.notification;
      if (!title && !body) {
        title = data.title;
        body = data.body;
      }

      const notification: Notification = notificationOpen.notification;
      //firebase.notifications().removeDeliveredNotification(notification.notificationId);
      this.handleNotificationActions(
        title,
        body,
        data,
        navigator,
        t,
        "background"
      );
    }
