Draggable slider with Multi-Image field

I’m trying to build a draggable slider that dynamically pulls in images from a collection item multi-image field.

I’ve used https://tutorial-dynamic-slider-multi-image.webflow.io/ to get the multi-image field pull through to a default slider, but it doesn’t seem to be draggable on desktop (just tablet/mobile).

Has anyone found a way to customise something like this? Seems like such a basic thing…
