Lightbox CMS Collection

Design help Custom code
1

I wanted to make it so that you could add new brands and upload videos through cms without entering the layout itself. To do this, I created 2 collections and combined them with a code, that is, videos that have the brand name in the settings are immediately pulled into the appropriate group. But: they do not pull up the lightbox - this is what makes it possible to open the video view limited to one brand.
To merge the two collections, I used this code:

<style>
.tr-item {display: inline-block;}
.tr-contain{display:block !important;}
.slick-prev:hover,
.slick-prev:focus,
.slick-next:hover,
.slick-next:focus
{
    outline: none;
}
.slick-slide, .slick-slide *{ outline: none !important; }
</style>

<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/slick-carousel@1.8.1/slick/slick.min.js"></script>

<script>


// when document is fully loaded
$( document ).ready(function() {


$('.tr-contain').slick({
  dots: false,
  speed: 1000,
  infinite: false,
  slidesToShow: 6,
  slidesToScroll: 1,
  arrows: false,
  touchThreshold:300,
  responsive: [
    {
      // tablet
      breakpoint: 991,
      settings: {
        slidesToShow: 2
      }
    },
    {
      // mobile portrait
      breakpoint: 479,
      settings: {
        slidesToShow: 1
      }
    }
  ]
});

$('.slider-prev').click(function(){
    $(this).closest('.swiper').find(".tr-contain").slick('slickPrev');
});

$('.slider-next').click(function(){
    $(this).closest('.swiper').find(".tr-contain").slick('slickNext');
});


});


</script>

Can someone help me either update this code or give me some advice on how to make the videos group into lightbox groups by category?

P.S. I used the embedded code to display the video, because I need the video to play on the hover.

Thank you in advance!
