Woocommerce Mail Customizer – custom font info

Hello!

I follow this guide to add custom font:

https://villatheme.com/faqs/#faq-773166396

then i added this snippet:

add_action( ‘viwec_email_header’, function () {
?>
<link rel=”preconnect” href=”https://fonts.googleapis.com”&gt;
<link rel=”preconnect” href=”https://fonts.gstatic.com&#8221; crossorigin>
<link href=”https://fonts.googleapis.com/css2?family=Jost:wght@100;200;300;400;500;600;700;800;900&display=swap&#8221; rel=”stylesheet”>
<?php
} );

and this css:

td, th, p, span, div { font-family: ‘Jost’, sans-serif !important; }

Im using the PRO version but its not working, i checked by Gmail.
