You can add Status History Comment for the given order programmatically in Magento 2.
You must get the Order Id to add comments and load the order object. Here is the code to add a comment to the order with the comment we set as default. With this tutorial we add observer comments
Let’s create the events.xml file in the module under the path Magepow/HistoryOrderComment/etc.
<event name="checkout_submit_all_after">
<observer name="sales_products_observer_checkout_submit_all_after" instance="Magepow\HistoryOrderComment\Observer\OrderComment" />
</event>then add the file OrderComment.php called in the previous events.xml file

namespace Magepow\HistoryOrderComment\Observer;
use Magento\Framework\Event\ObserverInterface;
class OrderComment implements ObserverInterface
{
/**

*/
protected $historyFactory;
/**

protected $orderFactory;
/**

protected $_jsonHelper;
/**

*/
protected $_filterManager;
public function __construct(
\Magento\Framework\Json\Helper\Data $jsonHelper,
\Magento\Framework\Filter\FilterManager $filterManager,
\Magento\Sales\Model\Order\Status\HistoryFactory $historyFactory,
\Magento\Sales\Model\OrderFactory $orderFactory,
) {
$this->_jsonHelper = $jsonHelper;
$this->_filterManager = $filterManager;
$this->historyFactory = $historyFactory;
$this->orderFactory = $orderFactory;
}
public function execute(\Magento\Framework\Event\Observer $observer)
{
$comment = __('Order Comment: order comment');
$orderId = $observer->getOrder()->getId();
if ($orderId && (!empty($comment))) {
$order = $observer->getOrder();
if ($order->getEntityId()) {
$status = $order->getStatus();
$history = $this->historyFactory->create();
$history->setComment($comment);
$history->setParentId($orderId);
$history->setIsVisibleOnFront(1);
$history->setIsCustomerNotified(0);
$history->setEntityName('order');
$history->setStatus($status);
$history->save();
}
}
}
}This is the result after successful payment
Good luck .
