                return false;
            }
        });
    }
}

@Override
public int getItemCount() {
    return messageModels.size();
}

public class ReciverViewHolder extends RecyclerView.ViewHolder {
    TextView reciverMsg, reciverTime;

    public ReciverViewHolder(@NonNull View itemView) {
        super(itemView);
        reciverMsg = itemView.findViewById(R.id.receiver_message_text);
        reciverTime = itemView.findViewById(R.id.receiver_message_time);
    }
}

public class SenderViewHolder extends RecyclerView.ViewHolder {
    TextView senderMsg, senderTime;

    public SenderViewHolder(@NonNull View itemView) {
        super(itemView);
        senderMsg = itemView.findViewById(R.id.sender_message_text);
        senderTime = itemView.findViewById(R.id.sender_message_time);
    }
}

}

When I click "Delete for Everyone" in my chat application, the message is only deleted on the sender's side. It does not get deleted on the receiver's side.
