Change PHP firebase plugin and implement push notification badge count.

Hi, I need PHP firebase plugin to be changed so that I get one particular feature while other features remain the same. Push notification scheduler is already implemented in the backend and working in the App. I also need the badge count to be implemented so that when push notification come, I would get badge count in the mobile App. *Please read carefully what I need* Experience CodeIgnitor developer who have good experience working on push notification using firebase can bid.
