AceAbility, AceDataAbility, AceServiceAbility

public interface IAssistanceChannel

Provides methods to receive notifications about collaboration session establishment and disconnection returned by the framework to your application.

When a collaboration session is established, terminated during establishment, or disconnected, the framework notifies your application through the IAssistanceChannel callback.

When your application calls the Ability#startAssistAbility method to establish a collaboration session, IAssistanceChannel needs to be passed, and the peer ability of the collaboration session needs to implement the IAssistanceChannel API.
