Linking to a Specific Tab from Other Page and Menu

Design help Custom code

Hi Community.

I used custom code from topic Linking to Specific Tab from another Link or Button

Custom code I added

<script>
  $('.custom-button-1').on('click', function (evt) {
    $('.target-tab-link-1').triggerHandler('click');
  });
  $('.custom-button-2').on('click', function (evt) {
    $('.target-tab-link-2').triggerHandler('click');
  });
  $('.custom-button-3').on('click', function (evt) {
    $('.target-tab-link-3').triggerHandler('click');
  });
  
  var Webflow = Webflow || [];
Webflow.push(function () {
  var tabName = getParam('tab');
  if (!tabName) return;

  $('.' + tabName).triggerHandler('click');

  function getParam(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
      results = regex.exec(location.search);
    return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
  }
});
</script>

I can’t understand how to change the code to make it work. Can you help me with that please? Thank you.
