I created a trigger which captures clicks on buttons using Google Tag Manager, and my buttons have nested divs and they look like this in dev tools:

and they render like this:

I want to capture the ID on the parent div i.e. confirm-09:00:22:00 in the GTM variable. The problem I am facing is that if a user clicks on padding around Confirm Timeslot text, the ID is captured correctly, but if the clicks happens on the Confirm Timeslot text itself, the ID is empty. How can I make sure that the ID is always captured regardless of where user clicked on the button? Thanks
