  if (!(self.Notification && self.Notification.permission === "granted")) {
    return;
  }

  const data = event.data?.json() ?? {};
  const title = data.title || "Something Has Happened";
  const message =
    data.message || "Here's something you might want to check out.";
  const icon = "images/new-notification.png";

  const notification = new Notification(title, {
    body: message,
    tag: "simple-push-demo-notification",
    icon,
  });

  notification.addEventListener("click", () => {
    clients.openWindow(
      "https://example.blog.com/2015/03/04/something-new.html",
    );
  });
