To delay displaying the next button on a specific node, simply add the script below to the node-level script area. You can adjust the delay time by updating the timeBeforeDisplay in milliseconds.

<script>
  let timeBeforeDisplay = 5000;
  let nextButton;

  let checkBtn = setInterval(() => {
    if (document.getElementsByClassName('next-btn')[0]) {
      nextButton = document.getElementsByClassName('next-btn')[0];
      nextButton.style.display = 'none';
      clearInterval(checkBtn);
    }
  }, 30);

  setTimeout(() => {
    nextButton.style.display = 'inline-block';
  }, timeBeforeDisplay);
</script>
