Additional context

Exact dummy snippet throwing an error, borrowed from the example repositories:

if (Notification.permission == "default") {
        Notification.requestPermission().then((response) => {
            if (response === "granted") {
              console.log("OK")
            } else {
              console.log("Permission is " + response);
            }
          })
      }
