Gallery Section Auto Scroll Not Working

Hi, I have a gallery section featuring logos on the Homepage. I was using the code below to force it to auto scroll (that is pasted in page settings > advanced) and it was working just fine, now it seems to not be working. I have tweaked it here and there but can not figure out what made it stop working. For reference, this particular gallery does not have a "auto scroll" option built in, so this code is an attempt to force it to scroll. 

<script>
    /**
    *  Gallery Section Auto Scroller
    **/
  (function () {
    setAutoScroll({
      gallery: 1,
      direction: 1,
      timing: 3000,
      ;
    });

    /*
    * Copy and paste the above code
    * to target more auto-scrolling
    * sections
    **/

    /** gallery
    * gallery section order on the page. Ex:
    * 1 = the first gallery section on a page,
    * 2 = the second gallery section on a page
    **/

    /** direction
    * direction the gallery should go in.
    * 1 = backwards,
    * 2 = forwards
    **/

    /** timing
    * timing between each slide, in milliseconds. Ex:
    * 2000 = 2 seconds
    **/

    function setAutoScroll(settings) {
      function init() {
        let section = document.querySelectorAll(".page-section.gallery-section")[settings.gallery - 1];

        function clickArrow() {
          if (section && !document.querySelector("html.sqs-modal-lightbox-open") && !document.hidden && !document.querySelector("body.sqs-edit-mode")) {
            let arrow = section.querySelectorAll(".gallery-reel-control .gallery-reel-control-btn")[settings.direction - 1];
            if (arrow) arrow.click();
          }
        }

        window.setInterval(clickArrow, settings.timing);
      }

      window.addEventListener("DOMContentLoaded", init);
    }
  })();


</script>

Have you got the scroll arrows enabled?
