I'm trying to track an element that appears after I click a button with GTM, but using Element Visibility trigger doesn't fire at all. I had GTM setup for some clicks and it worked fine, but I'm stumped with this Visibility trigger. I tried toggling Observe DOM changes but that didn't work. I thought maybe my CSS Selector is wrong so I changed it to body but that didn't work too. Is there anything I'm missing here?
The following picture is the settings for tracking body. This should fire when the page is loaded because normally all contents are displayed in body.
