Hi, Sorry for the slow reply.

  1. Give your button an id, say “my-button”.
  2. Give your lightbox an id, say “my-lightbox”.
  3. In your page settings, in the “before tag” section, add this code:

<script>

/* Intercept click of my-button
and trigger click of my-lightbox */ 

$(document).on('click', '#my-button', function(event) { 
event.preventDefault(); 
$("#my-lightbox").click(); 
});

</script>
