I'm currently implementing a Chat application using Firebase Cloud Messaging to send push notifications. Using the notification field in the API call, Firebase displays them automatically without having to manually create a service and listen for the messages.
The push notification is pretty generic, just says "You have a new message!", so it doesn't make sense to keep adding new pushes every new message, I need firebase to not show a new push if the message body contents the same of a previous one.
Is it posible to do without implementing the service and handling Notification show manually? Found no references of this use case in the documentation.
