How to detect click outside React APPLICATION? - reactjs

Question

I want a functional React component to close whenever the user clicks outside the application as well as outside the component within the application.
I've worked out how to close the component so long as the user clicks inside the containing application, but it still ignores clicks in an entirely different Windows application.
I want to emulate the behavior of the "Avatar" button at the top right of a Google Maps window. The button opens a modal dialog that is dismissed when the user clicks anywhere outside the dialog.
My current code has a useEffect hook that calls addEventListener and removeEventListener on the current document:
useEffect(() => {
const handleClickOutside = (event) => {
if (wrapperRef.current && !wrapperRef.current.contains(event.target)) {
onCloseButtonClick(event)
}
};
document.addEventListener("click", handleClickOutside, true);
return () => {
document.removeEventListener("click", handleClickOutside, true);
};
}, [onCloseButtonClick]);
I had hoped the solution was as simple as attaching addEventListener and removeEventListener on window instead of document, but it doesn't work.
How can I clear the visible property of the component when the user clicks outside the containing application?
Thanks in advance for your attention.

You probably need to also listen to onblur on the window. That can call the onCloseButtonClick straight away as theres no element attached to those events.
useEffect(() => {
const handleClickOutside = (event) => {
if (wrapperRef.current && !wrapperRef.current.contains(event.target)) {
onCloseButtonClick(event)
}
};
document.addEventListener("click", handleClickOutside, true);
window.addEventListener("blur", onCloseButtonClick, true);
return () => {
document.removeEventListener("click", handleClickOutside, true);
window.removeEventListener("blur", onCloseButtonClick, true);
};
}, [onCloseButtonClick]);
