How to check if an object is in view?

Question

JavaScript

The site has the smooth-scrollbar plugin (we change the scrolling behavior), and therefore I can’t track with the help of plugins such as wow, viewport.jquery, etc. whether the container is in the visibility zone and, accordingly, I can’t animate the desired div at the right time, when on this site - https://curenails.co/en-US/menus/facial everything works, although the scroll plugin is also installed
