Is possible to open lightbox on load page?

I dont know if there is UI option. At the end I create this Javascript Function

<script>
    // Simulate a click on the link when the page loads
window.onload = function() {
  var link = document.getElementById("videomodal");

  // Check if the link exists (important for safety)
  if (link) {
    link.click();
  }
};
</script>
