When the screen share is disconnected a notification will be shown.
A pop-up window on the ProctorExam page will then be displayed inviting the candidate to share once again their screen share as shown in the image below.
The candidate then needs to select the mirrored image of their screen inside of the pop-up and then select the 'Share' button. Failing to select the screen inside the pop-up first will not activate the 'Share' button.
