How to detect Tab close in web browser and Browser Reload in Angular?

My problem is , I need to remove a key in local storage when the browser tab is closed.

I used Host Listener with 'window:beforeunload' ,

@HostListener('window:beforeunload', ['$event'])
beforeunloadHandler(event) {
  // remove local storage key here
}

But , When tab is Reload it clear the key in local storage. In my problem session storage cannot be used.
