Disabling access to Inspect Element

Im trying to disable access to Inspect Element to prevent videos from being downloaded and etc…

import streamlit.components.v1 as components
import streamlit as st

my_js = """
document.addEventListener('contextmenu',(e)=>{
    e.preventDefault();
  }
  );
  document.onkeydown = function(e) {
  if(event.keyCode == 123) {
     return false;
  }
  if(e.ctrlKey && e.shiftKey && e.keyCode == 'I'.charCodeAt(0)) {
     return false;
  }
  if(e.ctrlKey && e.shiftKey && e.keyCode == 'C'.charCodeAt(0)) {
     return false;
  }
  if(e.ctrlKey && e.shiftKey && e.keyCode == 'J'.charCodeAt(0)) {
     return false;
  }
  if(e.ctrlKey && e.keyCode == 'U'.charCodeAt(0)) {
     return false;
  }
}
"""

# Wrapt the javascript as html code
my_html = f"<script>{my_js}</script>"

st.title("Example Text")
components.html(my_html)

This is the code I’m using. but it only works for a limited area.
Really appreciate a help
