title: Need authorization in a navigator.sendbeacon()
body: <p>My problem is that when i call a function who listen to the event onBeforeUnload(), i want to post a data. The problem is that my request is unauthorized. I need to add my bearer somewhere, but i don't know how.</p>
  
  <p>Here my actual code:</p>
  
  <pre><code>@HostListener('window:beforeunload', ['$event'])
    onBeforeUnload(): void {
       navigator.sendbeacon(`${localhost:8080/apiRest}`, infoIWantToSent);
    }
  </code></pre>
  
  <p>For now, the request send a 401:unhautorized, which is normal, since i don't transmit any bearer.</p>
