        LoggerInterface $logger
    ) {
        $this->historyRepository = $historyRepository;
        $this->logger = $logger;

    /**
     * load sales order status history by comment id
     *
     * @param int $commentId
     * @return OrderStatusHistoryInterface|null
     */
    public function loadComment(int $commentId): ?OrderStatusHistoryInterface
    {
        $historyCommment = null;
