Once the encryption protocol has been completed successfully, authentication the connection using the registered DeviceProvider from the ClientProxy. For the Nearby Presence MVP, this will be the PresenceDeviceProvider and will only support outgoing connections, which is why the responder role is not used. The result (success or failure) is passed back to callers via the EndpointManager. See go/cros-nearby-presence-np-nc-authentication for details.
