I have a simple function that checks if CapsLock was on input

document.addEventListener('keydown', function(e) {
    if(e.getModifierState("CapsLock")) {
       console.log('CapsLock is on')
       } else {
         console.log('Capslock is off')
       }
  });

To test the function I tried to trigger it this way:

  document.dispatchEvent(new KeyboardEvent('keydown', {key:'A', capsLockKey: true}));

But it's not working

How can I trigger new Keyboard Event with CapsLock property?
