Solved myself, below is the code I used from another member: 
 
<script>
  document.addEventListener("DOMContentLoaded", function () {
    // configure the classes we're looking for
    const listClass = "div.gallery figure";
    const linkClass = "div.gallery-strips-item-wrapper a, div.gallery-grid-item-wrapper a, div.gallery-masonry-item-wrapper a";
    const lightBoxCaption = "lightbox-caption";
    const lightboxSlideSelector = "div.gallery-lightbox-list figure[data-slide-url='{0}']"
    // select all gallery elements, find their captions
    // if they exist then extract the slide id and add a new caption element
    // to the lightbox slide
    const n = document.querySelectorAll(listClass);
    for (var i = 0; i < n.length; i++) {
      const a = n[i].querySelector(linkClass);
      const c = n[i].querySelector("figcaption");
      if (a && a.href && c) {
        const id = a.href.split("=")[1];
        const lbSelector = lightboxSlideSelector.replace("{0}",id);
        const lb = document.querySelector(lbSelector);
        const cp = document.createElement("figcaption");
        cp.className = lightBoxCaption;
        cp.innerHTML = c.innerHTML;
        lb.appendChild(cp);
      }
    }
  });
</script>
<style>
figcaption.gallery-caption {
  display:none;
}
figcaption.lightbox-caption {
  bottom:0;
  font-family: "Europa", serif;
  font-style: regular;
  font-size: 16px;
  line-height: 1.4em;
  color: #061A37;
  text-align:justify;
}
</style>
