Horizontal Scroll On Image Gallery Slideshow

Hi, I'm sharing a site I'm doing for a client. She was looking to have her image gallery on the bottom of her home page move to the left upon scroll. Is there any way to do this within Squarespace? I tried two different gallery setups (as you can currently see on the site) with no luck. 

The Gallery slideshow reel section is very similar to the look I want, however, the images move upon click instead of scroll. 

Here is the photo she shared with me for inspiration: https://www.tarynkent.com/

By "move left upon scroll," do you mean that as the visitor scrolls down the page, the galley moves left, and as they scroll up, it moved right? If so, there's not a way to configure that just with settings. You would need some custom code.

Yes exactly - when their cursor is on that gallery section I suppose. If you take a look at the website I linked as inspiration, I would want the gallery to mimic the one on there.
