Значек с общим количеством уведомлений

Question

Приложение получает уведомления через FirebaseCloudMessaging

Хочу установить значек внутри приложения и на нем цифры с общим количеством новых уведомлений. Значек установить нет проблем. но как передавать на него количество всех новых уведомлений?? хотел установить слушатель но в интернете не нашел подходящей информации, в основном пишут про слушатель всех приложений. а нужно только прослушивать мой канал уведомлений
