        alert("This browser does not support desktop notification");
      } else if (Notification.permission === "granted") {

          data['body'] = "notification's body";
          var notification = new Notification(data['title'], {

          }
      } else if (Notification.permission !== "denied") {
        Notification.requestPermission().then(function (permission) {
          if (permission === "granted") {
            var notification = new Notification("really");

        });
      }
    }
</script>

Answer 1

Is your website served using https:// - because Chrome has deprecated Notifications API on insecure (eg http:// ) origins

Otherwise, your code works just fine in Chrome

Answer 2

HTTPS (Chrome default mode)

localhost debug

HTTP

chrome://settings/content/notifications
