When a Service ability is connected, the **onConnect()** callback is invoked and returns an **IRemoteObject** defining the proxy used for communicating with the Service ability. OpenHarmony provides a default implementation of the **IRemoteObject** interface. You can extend **rpc.RemoteObject** to implement your own class of **IRemoteObject**.
