I have a csv file with 3 columns ( Order#|Carrier|Tracking), how do i add the tracking numbers programmatically by reading the csv file through a script?

there are some reference here, but i'm not exactly sure how to put it together ( how to declare trackfactory, shipment etc)
How do I add tracking number to current order shipment in Magento 2?

$data = array(
 'carrier_code' => 'ups',
 'title' => 'United Parcel Service',
 'number' => 'TORD23254WERZXd3', // Replace with your tracking number
);

$track = $this->trackFactory->create()->addData($data);
$shipment->addTrack($track)->save();

below is the script i use to update quantity programmatically through reading an csv file for reference:

<?php $file = fopen('pub/media/files/inventory.csv', 'r', '"'); // set path to the CSV file
if ($file !== false) 

 require __DIR__ . '/app/bootstrap.php';
 $bootstrap = MagentoFrameworkAppBootstrap::create(BP, $_SERVER);

 $objectManager = $bootstrap->getObjectManager();

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

 // used for updating product info
 $productRepository = $objectManager->get('MagentoCatalogModelProductRepository');

 // used for updating product stock
 $stockRegistry = $objectManager->get('MagentoCatalogInventoryApiStockRegistryInterface');

 // add logging capability
 $writer = new ZendLogWriterStream(BP . '/var/log/import-update.log');
 $logger = new ZendLogLogger();
 $logger->addWriter($writer);

 // enter the number of data fields you require the product row inside the CSV file to contain
 $required_data_fields = 2; //change for 3 to 2

 $header = fgetcsv($file); // get data headers and skip 1st row

 while ( $row = fgetcsv($file, 5000, ",") ) 

 $data_count = count($row);
 if ($data_count < 1) 
 continue;
 

 $data = array();
 $data = array_combine($header, $row);

 $sku = $data['sku'];
 if ($data_count < $required_data_fields) 
 $logger->info("Skipping product sku " . $sku . ". Not enough data to import.");
 continue;
 

 $qty = trim($data['qty']);
 //$price = trim($data['price']);

 echo 'Updating product SKU: '.$sku.', with Qty: '.$qty.'<br />n'; // .' and Price:'.$price.'<br />';
 /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////updating price/////////////////////////////////////////////////////////////////////
 //try 
 // $product = $productRepository->get($sku);
 // 
 //catch (Exception $e) 
 // $logger->info("Invalid product SKU: ".$sku);
 // continue;
 //
 //
 // You can set other product data with $product->setAttributeName() if you want to update more data
 //if ($product->getPrice() != $price) 
 // $product->setPrice($price) 
 // ->setStoreId(0) // this is needed because if you have multiple store views, each individual store view will get "Use default value" unchecked for multiple attributes - which causes issues.
 // ->save();
 //
 /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////updating quantity/////////////////////////////////////////////////////////////////////
 try 
 $stockItem = $stockRegistry->getStockItemBySku($sku);
 
 catch (Exception $e) 
 $logger->info("Invalid stock for product SKU: ".$sku);
 continue;
 

 if ($stockItem->getQty() != $qty) 
 $stockItem->setQty($qty);
 if ($qty > 0) 
 $stockItem->setIsInStock(1);
 
 if ($qty < 1) 
 $stockItem->setIsInStock(0); //clean up first time
 
 $stockRegistry->updateStockItemBySku($sku, $stockItem);
 
 
 fclose($file);
