Modify html5 video player

Hi,

It’s a awesome plugin I love to use.

Currently, I face an issue that I want to hide the download link in HTML5 video player. (I bought the add-on upload file)

I try to use script code to add attribute, but it doesn’t work.

<script>
  document.querySelectorAll("video")[0].setAttribute("controlslist", "nodownload"); 
</script>

Does any one can help me?

Thank you ??
