 Components of the main calling screen:
 
 - **Media Gallery**: The main stage where participants are shown. If a participant has their camera enabled, their video feed is shown here. Each participant has an individual tile which shows their display name and video stream (when there is one)
 - **Header**: This is where the primary call controls are located to toggle settings and participant side bar, turn video and mix on/off, share screen and leave the call.
-- **Side Bar**: This is where participants and settings information are shown when toggled using the controls on the header. The component can be dismissed using the 'X' on the top right corner. Participants side bar will show a list of participants and a link to invite more users to chat. Settings side bar allows you to configure microphone and camera settings.
