Create post-event trigger for Zapier to pull attendees back into AMS

We are using Zapier (and iAppConnector) to connect Zoom with iMIS. We can successfully create a Zoom event (meeting or webinar) in iMIS Events already.

We want to be able to import meeting and webinar ATTENDEES (post event) back into iMIS (for Engagement scoring, follow-up communications, and more), but there is no trigger currently in Zoom that would allow us to create a Zap to run the process automation. We came up with a manual work around (download the .csv and upload it into a Google Sheet, and then the Zap is set up to run from there), but it sure would save that manual step if Zoom created a trigger!
