When using fab fa-whatsapp fontawesome icon, the Whatsapp brand isnt displayed

[Ferexbo]

Understanding that the fontawesome version used in hivepress is 5.13.1 and if I use
<i class="fab fa-whatsapp" aria-hidden="true"></i>
would work for me, it doesnt

Enlight me please how to do it in the right way, thank you for your help

I had to add the following code to the functions.php file:

function load_font_awesome_brands() {
   // Enqueue the full Font Awesome library to include Brands
   wp_enqueue_style('font-awesome-brands', 'https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.15.4/css/all.min.css', array(), '5.15.4');
}
add_action('wp_enqueue_scripts', 'load_font_awesome_brands');
?>
