Where is the popup file of the Bitrix window located? After clicking on the "Add to cart" button, a pop-up window opens, I need to make some corrections there. I understand that the question is very primitive) but I can’t find this file in any way.

1. It is worth clarifying which template you are using (I assume that the standard store)
2. Where exactly in the section? on the item card? The fastest way is in their template and there is the code you need in script.js
3. There is a global search in the Bitrix admin panel in files, but it's even better to use PhpStorm and a global search for the project.
4. Also, no one canceled the developer tools in the browser, you can see all the event handlers on the element and see where they are called and what they do.
