Add or remove a connection delegate

To detect changes in the connection status of a client app, register a connection delegate ConnectionDelegate with its unique user-defined ID.

If you want to stay informed of changes related to the Sendbird server connection status and notify the changes to different client apps, define and register multiple connection delegates to each view controller.

Connection event types

List of connection events

Method	Invoked when	Notified devices
didConnect(userId:)	The SDK has connected with the given `userId`.	The device that was connected to the server.
didDisconnect(userId:)	The SDK has disconnected for the `userId`.	The device that was disconnected from the server.
didStartReconnection	The SDK has started reconnecting to the Sendbird server.	The device where `connect(userId:authToken:completionHandler:)` was automatically called by the Chat SDK or manually by the client app.
didSucceedReconnection	The SDK has succeeded in reconnecting to the Sendbird server.	The device that successfully reconnected to the server.
didFailReconnection	The SDK has failed to reconnect to the Sendbird server.	The device that failed to reconnect to the server.
