Code for an inlay popup - to track events in GA

Hi everyone, We are trying to track through Google Analytics an inlay popup that loads an external form, however for some reason we can't track/see it in Google Analytics. Our goal is that every time someone clicks the overlay button, the click on the button should be captured in Google Analytics.
We already have the code, we would appreciate if anyone could help us to figure out the issue and correct the code
Best
Andy
