Information of the person sharing screen should be displayed to other members

[visharma-symbl]

Problem :-

During a conference meeting, when some shares the screen, the other meeting members are unable to identify whose screen is shared.

Expected behaviour :-

A message should be displayed on other meeting member's screen :- you are viewing "Person 1" screen
