Can i hide a dynamically created div to logged out users?

The body element already gets a logged-in class that you can use to hide the element with regular CSS.

body:not(.logged-in) #elementor-element-f4e5a8e {
  display: none;
}

If the ID is dynamic and isn’t always the same you’ll need a different selector to target the element, but that would still just require standard CSS techniques that have nothing to do with WordPress.

Also, be aware that hiding something with CSS is trivially easy for users to bypass, so whatever information is in this div should be treated as public.
