More control on push notifications

We need more control available on push notifications extensions

  • Ability to turn ON and OFF push notifications for all action messages
  • Ability to control template of push notification sent for action messages
  • Ability to individually turn ON and OFF push notification for each action message
  • Ability to control push message for custom messages through REST APIs and SDKs.

Is this open source? Can we extend a feature and submit a pull request?
