System notifications can be activated in the monitoring view by clicking the bell icon in the top right corner.

If the bell icon is blue, it is already activated.

Troubleshooting

Nothing happens when I click the bell icon

If nothing happens when you click on the bell icon, it may be because you have previously blocked notifications in your browser's settings.

To enable notifications, you can click on the controls next to the web address and ensure that Notifications are enabled (as shown in the image below). After that, you should be able to click on the bell icon within Exam.net again.
