I think I found the code I need to change in the

  <div class="button{if $additional_button_class} {$additional_button_class}{/if}" title="{$title|default:$button_title|escape}" onclick="{$div_link}">
    <a href="{$href}" onclick="{if $js_link}{$js_link};{else}javascript:{/if} if (event) event.cancelBubble = true;"{$reading_direction_tag}>{$button_title|amp}</a>
  </div>

I think the <a href...> needs to be changed to <a href="{$url}" class="see-details">

But that didn't work either lol
