Automatically download PDF after form submit

Good day to all!

Help me solve the problem.
I need the presentation PDF file to start downloading automatically to the client’s computer after sending the form, or a new window to open with the downloaded file.

With a standard redirect, the file opens in the same window and exits the page, thus creating the possibility of losing the client.

The chatGPT gave such a solution, but it does not work.

<script>
  document.addEventListener('DOMContentLoaded', function() {
    
    var formElements = document.querySelectorAll('.metform-form-content'); 

    formElements.forEach(function(formElement) {
     
      document.addEventListener('metform_after_submit', function(event) {
        
        setTimeout(function() {
          
          var fileUrl = 'https://yourwebsite.com/uploads/yourfile.pdf';

          
          var link = document.createElement('a');
          link.href = fileUrl;
          link.setAttribute('download', '');
          document.body.appendChild(link);
          link.click();я
          document.body.removeChild(link)
        }, 1000);
      });
    });
  });
</script>

Thank you
