Help with getting share-video info to appear

This code works on another page, but I’m trying to use it on a new page. I believe I have copied all that is needed, but it does not display the share-video form. I don’t know a lot about javascript so, I thought I’d start here.

$(function () {
   $('#share-video').on('click', function(event) {
      event.preventDefault();
      $('.share-video').toggleClass('hidden');
   });
<div>
<button class="btn-share" id="share-video"><svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"><path fill="currentColor" d="M18,16.08C17.24,16.08 16.56,16.38 16.04,16.85L8.91,12.7C8.96,12.47 9,12.24 9,12C9,11.76 8.96,11.53 8.91,11.3L15.96,7.19C16.5,7.69 17.21,8 18,8A3,3 0 0,0 21,5A3,3 0 0,0 18,2A3,3 0 0,0 15,5C15,5.24 15.04,5.47 15.09,5.7L8.04,9.81C7.5,9.31 6.79,9 6,9A3,3 0 0,0 3,12A3,3 0 0,0 6,15C6.79,15 7.5,14.69 8.04,14.19L15.16,18.34C15.11,18.55 15.08,18.77 15.08,19C15.08,20.61 16.39,21.91 18,21.91C19.61,21.91 20.92,20.61 20.92,19A2.92,2.92 0 0,0 18,16.08Z" /></svg> {{LANG share}}</button>

            </div>

Can you make a suggestion as to what I might be missing to get the share links to appear/display?

any help is appreciated
