How to send messages from service worker to the chrome extension without having the webapp open

In the background script we have:

chrome.webRequest.onBeforeRequest.addListener(function (details) {
  if (details.method === 'HEAD') {
    if (details.url.endsWith('?start')) {
      ringSound.play();
    } else if (details.url.endsWith('?stop')) {
      ringSound.pause();
 ringSound.currentTime = 0;
