Hello @gad123,
You can add this by using custom JS and CSS, please put the CSS below in Customizing > Custom CSS/JS:
Part II(jQuery):
jQuery(document).ready(function(){
jQuery(".oceanwp-about-me-social").append('<li class="whatsapp"><a href="#" aria-label="WhatsApp" target="_blank" rel="noopener noreferrer"><i class=" fab fa-whatsapp" aria-hidden="true" role="img"></i></a><span class="screen-reader-text">Opens in a new tab</span></li>');
});
Part II(CSS):
.oceanwp-about-me .oceanwp-about-me-social li.whatsapp {
background: #25D366;
border-radius: 100px;
}
Please read this link for more information about the CSS/JS code on the customizer: https://docs.oceanwp.org/article/354-add-custom-css-and-js-to-your-website.
Note 1: If you have any cache plugin or server cache(CDN / Browser Cache and Cookies and …), you need to clear its cache contents or disable them to see your changes. Also, remember to click on the regenerate all assets file and data in Elementor > Tools(if you have Elementor).
Note 2: To edit the link, change the “href” value; here: https://postimg.cc/JshT9xhw.

I hope that helps.
Best Regards
