Is there any way to add link in order details page at shipment section?

Potential backward compatibility issues in Joomla 4 https://docs.joomla.org/Potential_backward_compatibility_issues_in_Joomla_4#Plugins_.28Events.29

im trying to develop a plugin in php Joomla Virtuemart and i m stack how to call/execute it .

Php 8.2 Joomla 5.2 / VM 4.4

I m trying to get virtuemart ids and quantity from the order details page and parse values via link method to another page. I m trying to show the link below items of order and in shipping section

the following links does not show

i dont know if i use the correct class and or the event/trigger ?

<?php
defined('_JEXEC') or die('Restricted access');

use Joomla\CMS\Plugin\CMSPlugin;
use Joomla\CMS\Factory;

class plgSystemSomething extends CMSPlugin
{
    public function plgVmOnShowOrderBackend($virtuemart_order_id, $orderData)
    {
        // URL Order id
        $orderLink = JRoute::_('index.php?option=com_virtuemart&view=orders&task=edit&virtuemart_order_id=' .  $virtuemart_order_id, false);

        // HTML show the link
        $html = '<div style="margin-top:15px; padding:10px; border:1px solid #ddd; background:#f9f9f9;">
                    <strong>Here :</strong> 
                    <a href="' . $orderLink . '" target="_blank">Links of order  #' . $virtuemart_order_id . '</a>
                 </div>';

        return $html;
    }
}

I temporary use this method

       $app = Factory::getApplication();

   if ($app->isClient('administrator') && 
($app->input->get('option') == 'com_virtuemart') && 
($app->input->get('view') == 'orders') && 
($app->input->get('virtuemart_order_id'))) { do }

that worked for me

<?php
defined('_JEXEC') or die;

use Joomla\CMS\Factory;
use Joomla\CMS\Plugin\CMSPlugin;
use Joomla\CMS\Uri\Uri;


if (!class_exists('VmConfig')) {
    require(JPATH_ROOT . '/administrator/components/com_virtuemart/helpers/config.php');
}
if (class_exists('VmConfig')) {
    VmConfig::loadConfig();
}

// creating the plugin class 
class plgVmShipmentProds2boxes extends vmPlugin
{
    function __construct(&$subject, $config)
    {
        parent::__construct($subject, $config);

        // Loading plugin Joomla parameters
        $this->website = $this->params->get('value1', '');
        $this->username = $this->params->get('value2', '');
        $this->serial = $this->params->get('value3', '');
    }

    /**
     * VirtueMart Call this function at backend οrder page.
     */
    public function plgVmOnShowOrderBEShipment($orderId, $order)
    {
        $this->Prods2Boxes($orderId, $order);
    }

    /**
     * Custom function for data process
     */
    private function Prods2Boxes($orderId, $order)
    { ....
