react-native-notifications: When the app is on the background, the "registerNotificationReceivedBackground" event is not fired

Using the last version, 3.1.1, when the app is on the background, the registerNotificationReceivedBackground event is not fired.

The documentation says it’s supported but it’s not working (https://wix.github.io/react-native-notifications/docs/general-events#registernotificationreceivedbackground)

Notifications.events().registerNotificationReceivedBackground(
  (
    notification: Notification,
    completion: (response: NotificationCompletion) => void,
  ) => {
    console.log('Notification Received - Background', notification.payload);

    // Calling completion on iOS with `alert: true` will present the native iOS inApp notification.
    completion({
      alert: false,
      sound: false,
      badge: false,
    });
  },
);

Besides this, the registerNotificationReceivedForeground event is working as expected.
