There is no msgId on event data that triggered

I’m sending a message to WhatsApp via the API and want to get the delivery status update via a journey triggered by the campaign-notification-updates event instead of using the postbackURL on engage preference.

But I don’t get msgId like in postbackURL, I only get data like this:

I get this data from node function by returning value from data.event. Can I get the msgId here?

hi team, could you help us on this. How to mapping data from this event into campaign message?

please answer Engage team
