connect

Attempts to connect the chat session using existing configuration, the attempt will be made on background thread. Successful connection will be announced to the ChatStateListener.onConnected which was supplied in ChatBuilder. If there is an issue during/after reconnection the ChatStateListener.onUnexpectedDisconnect will be called, it is responsibility of application to perform a repeated reconnection attempt, if it is desirable. Reconnect attempts should be performed only if the device is connected to the internet. If the repeated reconnection attempts are made, they should be called with exponential backoff, in order to prevent backend overload.
