Simple video call application- using React JS, Node JS, webRTC and Socket.io

an application to initiate a video call between tow users by sharing thier id
one of them will be the host of the call (who instantiate it) and he has the ability to change the other user background image
(not done in this during the limitation of time from my side) and the reciever will be normal user, each user have the ability
to turn on/off the mic or camera at any time and also can hang up the call
