You will need to copy the header.php file into the child theme and then where the social coding begins, add the code the plugin documentation states:
You will need to put this somewhere within this location of the header.php
….either at the beginning or just before the closing tag. You might have to put that code in a span container or something that will allow you to style it or position it using CSS. The rest will basically be up to you. Ultimately you can use that plugin code (above) to put it almost anywhere in a theme’s template file.
