How to know when a player disconnects?

using UnityEngine;  
using Normal.Realtime;  
  
public class PlayerConnectionManager : MonoBehaviour {  
    private RealtimeAvatarManager _manager;  
  
    private void Awake() {  
        _manager = GetComponent<RealtimeAvatarManager>();  
        _manager.avatarCreated += AvatarCreated;  
        _manager.avatarDestroyed += AvatarDestroyed;  
    }  
  
    private void AvatarCreated(RealtimeAvatarManager avatarManager, RealtimeAvatar avatar, bool isLocalAvatar) {  
        // Player joined - you can show feedback here
        Debug.Log($"Player joined: {avatar.gameObject.name}");
    }  
  
    private void AvatarDestroyed(RealtimeAvatarManager avatarManager, RealtimeAvatar avatar, bool isLocalAvatar) {  
        // Player disconnected - show feedback here
        Debug.Log($"Player disconnected: {avatar.gameObject.name}");
    }  
}
