Look into querying the activity log for that item_id, and a to/from date that encompasses the triggerTime with some buffer to each side (a 1 minute window should suffice). Then scan what comes back for one with an ID that matches originalTriggerUuid.

I am not making a promise this works, as I haven’t implemented it before. I do not know for a fact that the trigger IDs align with the activity logs. I’m only suggesting this as a path of investigation you could use to discover if they in fact do align (and report back here your findings)
