Popup Hero Exit Intent

I have a pop-up that I want to be triggered via exit intent, but it’s not working.

I’ve connected my website, I’ve selected “show via a trigger”, and I’ve selected a condition of “on exit intent”.

I’ve added the instant embed code to my site, in the correct place.

The only thing I’m unclear about is the Trigger Code:

Answerly.trigger(‘PopupHero’, ‘ea774aff-e187-400c-9f7c-24367fcb6147’);

What am I meant to do with this (if anything), and where should it go?
