Help with Products in Ecom feature

Hello I am having a hard time figuring out how to create a page like this on webflow

https://www.chromeindustries.com/product/barrage-cargo-backpack/BG-163.html?dwvar_BG-163_color=ALLB&dwvar_BG-163_size=NA&cgid=view_all_bags

I cant get the products to change image when choosing the variant like on this site

Any help would be appreciated!
