Chat Invite And Accept Notification When a visitor initiates a chat on the website, the system detects the incoming request. At the same time, if the user is using his mobile app and is currently online, he'll immediately receive a notification alerting him to a new chat request. When a visitor sends a chat, the user will receive the option to either accept or decline it on the "Visitors" screen on the user's side.. If the user accepts the chat, the visitor will receive a message indicating that the user has joined the chat. From there, they can communicate with each other.
