Privacy of information sent via FCM

[WizWareTech]

What data is sent to FCM? Is it JUST a generic 'you have an alert' or does it actually contain specific information from the item that was posted or who posted it?

The reason I am asking is because we have a client that has a private instance of HumHub with confidential information regarding their software development that can't leave their instance, but they do want to have FCM-based notifications.

If the plugin does sent something other than a generic notification, then my suggestion is to make this a configurable item for the plugin that someone can enable generic notifications to keep information from leaking.
