Content Card click trigger IAM

I want to create a flow of a customer clicking on a Content Card in our App which instantly triggers an IAM.

The logical solution is for the Content Card click to log an Event. Then a separate campaign triggers the IAM based on the Event being updated. Problem is in testing it works on some devices and not for others maybe due to Events being updated in the user profile is delayed. You could create a Canvas with an Action Path to look for "Click content card", but the IAM will trigger in the next session. Any ideas?

Thanks
