How to set up in tag manager to keep track who provided the email address in chat box then pass to GA/Adwords as conversion.

Hi,

We are upgraded to GA4 and the site already captures data in GA4, we would like to set up the tag manager to capture the INTERCOM event like someone “provided email address” on the chat will treat as one conversion and would track that in Google Analytic and also pass to Google Adwords as successful conversion.

I go through the articles about setting up tag manager in GA4 and am still a bit confused, I only need to keep track of the event of “provided email address”

Does anyone have better instructions on this matter?

Thanks,
