      onCallCancelled

      The call was canceled by the inviter or timed out. This callback is received by an invitee. You can listen for this event to determine whether to show a missed call message.
      This indicates that the call was canceled by the caller, timed out by the callee, rejected by the callee, or the callee was busy. There are multiple scenarios involved. You can listen to this event to achieve UI logic such as missed calls and resetting UI status.
      Call cancellation by the caller: The caller receives the callback (userId is himself); the callee receives the callback (userId is the ID of the caller).
      Callee timeout: the caller will simultaneously receive the onUserNoResponse and onCallCancelled callbacks (userId is his own ID); the callee receives the onCallCancelled callback (userId is his own ID).
      Callee rejection: The caller will simultaneously receive the onUserReject and onCallCancelled callbacks (userId is his own ID); the callee receives the onCallCancelled callback (userId is his own ID),
      Callee busy: The caller will simultaneously receive the onUserLineBusy and onCallCancelled callbacks (userId is his own ID),
      Abnormal interruption: The callee failed to receive the call ，he receives this callback (userId is his own ID).
      void onCallCancelled(String userId);
