callActionHandler property
Optional handler for in-call control actions (mute, speaker, camera).
If not provided, a default CometChatCallActionHandler is used,
which delegates all actions directly to NotificationVoipPlugin.
Provide a custom subclass to intercept actions — e.g., to mute a WebRTC audio track when the user toggles mute.
Implementation
final CometChatCallActionHandler? callActionHandler;
