The Divi theme lets you add social icons to the header and/or footer. However, the range of icons on offer is rather limited. Divi Booster includes a feature which vastly increases the choice of icons.
Adding Social Icons to the Header / Footer in Divi Booster
To use it, first enable social icons in the header or footer.
Then go to:
Divi > Theme Customizer > Divi Booster > Social Media Icons
From there you can add icons and set their target URLs, like so

Publish the changes and then when you view your site you'll see the icons added to either the header, or footer, alongside any of the built-in icons you have configured, like so:


Sorting the Social Media Icons
The order can be changed by dragging and dropping the icon boxes. The icons you add in Divi Booster will be placed after any of the built-in Divi icons you have set up (Facebook, Twitter, etc). If you need to sort these standard icons too, remove the built-in ones and instead add the equivalent icon from from within the Divi Booster setting. So, for example, if you wanted to have Facebook, then TikTok, then Twitter, you'd set the icons up like so:

Do the Social Icons Work in Extra?
Yes, the icons also work in Extra. Here's an example of how they look in the header and footer:
