WhatsApp on Social Menu

I’ve added Whatsapp on Social Menu adding this code on child theme functions-php: https://docs.oceanwp.org/article/365-add-new-social-options-for-the-top-bar-and-the-social-menu

For some reason even if I choosed the “colored” link style I have the black and white icon.
My website is https://www.masseriapapone.com

Thanks in advance
