Shipping Address missing from Order Confirmation email template after Upgrade to magento 2.4.3-p3

cc function existed in zend_mail class in lib folder.

public function addCc($email, $name='')
        {
            if (!is_array($email)) {
                $email = array($name => $email);
            }

            foreach ($email as $n => $recipient) {
                $this->_addRecipientAndHeader('Cc', $recipient, is_int($n) ? '' : $n);
            }

            return $this;
        }

For now i just edited core files.but we need to override to our local/community folder.I have created 2 arrays & 4 new functions for cc in info.php

<?php

}

In Mage_Core_Model_Email_Template_Mailer

public function send()
    {
        $emailTemplate = Mage::getModel('core/email_template');
        // Send all emails from corresponding list
        while (!empty($this->_emailInfos)) {
            $emailInfo = array_pop($this->_emailInfos);
            // Handle "Bcc" recepients of the current email
            $emailTemplate->addBcc($emailInfo->getBccEmails());
            $emailTemplate->addCc($emailInfo->getccEmails());
            // Set required design parameters and delegate email sending to Mage_Core_Model_Email_Template
            $emailTemplate->setDesignConfig(array('area' => 'frontend', 'store' => $this->getStoreId()))
                ->sendTransactional(

            );
        }
        return $this;
    }

add this function in Mage_Core_Model_Email_Template

public function addCc($cc)
    {
        if (is_array($cc)) {
            foreach ($cc as $email) {
                $this->getMail()->addCc($email);

        }
        elseif ($cc) {
            $this->getMail()->addCc($cc);
        }
        return $this;
    }
