i am trying to get tracking from csv and load to magento 2 order programmatically.
i grabbed the create shipment & add tracking code from here https://www.scommerce-mage.com/blog/magento-2-how-to-create-shipment-programatically.html, and add an execute function (line 122) to load data from csv. but i'm not sure how to create an shipment object (line 175).

<?php

$file = fopen('track.csv', 'r', '"'); // set path to the CSV file

if ($file !== false)

{

    require __DIR__ . '/app/bootstrap.php';

    $bootstrap = MagentoFrameworkAppBootstrap::create(BP, $_SERVER);

    $objectManager = $bootstrap->getObjectManager();

    $state = $objectManager->get('MagentoFrameworkAppState');

    $state->setAreaCode('adminhtml');

    // add logging capability

    $writer = new ZendLogWriterStream(BP . '/var/log/import-update.log');

    $logger = new ZendLogLogger();

    $logger->addWriter($writer);



    class ShipmentObject{

    /*There are two main functions 

    prepareShipment of MagentoSalesModelOrderShipmentFactory class which prepare invoice and 

    addObject of MagentoFrameworkDBTransactionFactory class which helps to create shipment and associate the shipment with original order in Magento 2.
