Connect to the bidirectional gRPC `MessagesStream` stream with the valid `sessionID` in metadata and send the message to the server with the `NewNotifyToken` [[ https://github.com/CommE2E/comm/blob/master/shared/protos/tunnelbroker.proto#L112 | field value ]].
The expected behavior is that the value will be written into the sessions table of the dynamoDB database into the `NotifyToken` field.
