Cancel a call invitation

Before an invitation is answered, the caller can cancel it with signalingCancel():

await openimsdk.signalingCancel({
  opUserID: currentUserID,
  invitation,
});

Pass the current user's ID and the complete SignalingInvitation for this call. Reuse the invitation data saved when the call was started; do not construct an incomplete object containing only roomID.

Resolving the Promise indicates that the cancellation signaling request has completed. The application should also end its local ringing or waiting state and release any unallocated media resources. Remote clients receive updates via SdkEvent.OnInvitationCancelled; see Handle call events for complete event listener and cleanup configurations.
