I'm playing with this javascript photo gallery, when you click a thumbnail (in the jsfiddle), the picture enlarges and via the javascript, can be swiped to the left/right with your finger on a smartphone, and I want to add the same functionality by using a mouse. (or add add previous/next buttons like on facebook pictures). Any idea how that can be done in this fiddle below?
<template>
<li>
<img alt="" loading="lazy">
</li>
