Hi
I have had a look at the plugin and it possable to create code to add the social icons.
But I am not going to add it the plugin as the plugin is not been used by many sites (20) so the effort to reward is too low. I have suggested to the plugin author that he might like to add support into his plugin
Otherwise if you wish to add support yourself look at this file to see how to add to the list output
You will need to set the global author and include or copy this file https://plugins.trac.www.ads-software.com/browser/stylish-author-bio/trunk/includes/author-social-media.php from author bio along with css
If you copy the code you can use the user that I pass in the filter ‘aa_user_display_extra’ rather than setting the global author witch would be better.
If you do add support I would look at taking a pull request to add it to the plugin
