Autoplay Carousel Items on Squarespace 7.0

Site URL: https://ievaviphoto.com/

I would love testimonials in the following pages to have an autoplay feature, however the code below doesn't work. Any insights why? I use summary blocks - carousel.

These are the pages I'm trying to add the code:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.0/jquery.min.js"></script>
<script>
  $(document).ready(function() {
    try {
     var container = Y.one("div#page-section-5f3e088ea1068224988e22e0"); /*change this to the slug of your page*/
     var gallery = Y.Squarespace.GalleryManager.getGalleryByContainer(container);
     gallery.setAttrs({
       "autoplay":true,
       "autoplayOptions": {
         "timeout":3000, /*make this higher to decrease speed, lower to increase it*/
         "randomize": true
       }
     });
   } catch (e) {
     console.error("Could not configure Gallery autoplay.", e);
   }
});
</script>

Hi. I see it worked here.
