New markers

All you need to do is paste this code into the "Execute JavaScript" trigger when the timeline starts.

let markers = document.querySelectorAll('[data-acc-text*="Marker"]');

markers.forEach(marker => {
  marker.addEventListener('click', () => {
    // Find the nested animation div within the clicked marker
    const animationDiv = marker.querySelector('.marker-animation.marker-animation-pulse');
    
    // If the animation div exists, remove it
    if (animationDiv) {
      animationDiv.style.display = 'none'; // You can also use animationDiv.remove() to completely remove it from the DOM
    }
  });
});

When you insert a marker on a slide, Storyline automatically assigns the word "Marker" to the Alt Text. The first line of code targets all objects that have "Marker" as the Alt Text. The function below listens for click events on all markers and removes the marker animation. This code will only stop working if you change the Alt Text for any reason. In that case, you would need to update the first line of code to reflect the new Alt Text.
