I have a click handler that I want to listen to any clicks on the window outside of my component:

  useEffect(() => {
    const handleOutSideClick = (event) => {
      if (!ref.current?.contains(event.target)) {
        setNavActive(false)
      }
    };
    window.addEventListener('keydown', handleOutSideClick, false);
    return () => {
      window.removeEventListener('keydown', handleOutSideClick, false);
    };
  }, [ref]);

However, I am getting the error:
Parameter 'event' implicitly has an 'any' type. (line 2)
and
Property 'contains' does not exist on type 'never'. (line 3)

How do I specify type in order to get this click handler working?
