Phone number in new order confirmation email

Hello,

OpenCart version 2.3.0.2.

I have used the following modification: https://www.opencart.com/index.php?rout ... n_id=11702

However, I want to display the customer's phone number in the email that he receives, and in the email that the admin receives.

How can I achieve this?

That extension should work without issue...

The extension is working fine with the invoice, but in email template (where <?php echo $shipping_address; ?> and <?php echo $payment_address; ?> are used) the phone number does not shows.
