If you do not want to view your own video while in session you can do so by using the 'pop out' feature in the call.
Step 1: Pop your Video Out
The pop out feature can be accessed by hovering over your own video until the Pop Out and Effects overlay appear.
Then click the Pop out button.
Your video will now appear smaller in the lower portion of your screen.
Step 2: Collapse your Video
You can either leave your video minimized for yourself, or hide it by first hovering over it until an arrow appears on the left hand side.
Clicking the arrow will collapse your video (or if already collapsed expand)
