gallery images with variation

I’m having trouble getting the plug-in to work as shown in the demo.

I’m attempting to have the images uploaded for each variation to show as the product gallery images. When a variation is selected, the gallery image would change to that image. Here is link to demo website that displays the correct behavior: https://demo.getwooplugins.com/woocommerce-variation-swatches/product-details/product/main-and-central-color/?plugin-tutorial-tab-color-demo=&attribute_pa_color=cognac

Please advise on how to have variation images appear in gallery.

Thank you!
