[In App Messaging] Ability to schedule campaign based on event bundle parameters

[Ethan1983]

What feature would you like to see?

Currently, in app message campaigns can be scheduled based on an event name. However, this isn't granular enough for generic events like screen_view.

How would you use it?

Campaign can be scheduled for a particular screen (identified by bundle parameter for the generic screen_view event)

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
