Can BookBub logo please be added to Customizing Social Media Icons

When I used the “Custom icon 1 URL” or “Custom icon 2 URL” area of “Customizing Social Media Icons” to add the BookBub logo & link to my Social Media Icons, it doesn’t work out well. I end up with…

1. A white BookBub logo instead of the sort-of grey ones to match yours
2. When I share my page amylu-riley.com/healing-testimony on Facebook, Facebook continues to grab the BookBub logo to share with that page (I don’t know why, and it’s still doing that, even after I removed the BookBub logo from the “Customizing Social Media Icons” area of my site.

Can you please add the BookBub logo to the main “Customizing Social Media Icons” menu? (I’m an author, and BookBub has over 10 million members, so I think it would be a good link for me to include.)
