Where is the ajax processing of the image slide in the Aspro max product list?

Question

JavaScript

Hello!
I made a slide using slick, at the request of the client I replaced the standard slide of product pictures in the product list with the one in the screenshot. But when changing the color of the parameters, the picture changes with the help of ajax, but the arrows and indicators (dots) disappear ...



Tell me, please, where is the ajax file handler that works when you click on the color? ..
