You can see your upcoming session by clicking on the webcam icon at the upper-right-hand side of the page (see image below).
From the pop-up window, you can also test the platform to make sure everything is set up correctly for your session.
When the session is due in 24-hour time, a countdown timer will appear on the icon.
When the session is about to start, the icon starts flashing on and off.
You connect to the platform and you start your session. Enjoy!
