// request permission on page load
document.addEventListener('DOMContentLoaded', function () {
  if (Notification.permission !== "granted")
    Notification.requestPermission();
});

function notifyMe(notificationText,notificationTitle) {
  if (!Notification) {
    alert('Desktop notifications not available in your browser. Try Chromium.');
    return;
  }

  if (Notification.permission !== "granted")
    Notification.requestPermission();
  else {
    var notification = new Notification(notificationTitle, {
      icon: '/images/chut-logo.png',
      body: notificationText,
    });

    notification.onclick = function () {
      window.open('http://localhost:3000/');
    };
