Hello, @DropShop,
1. Actually, in that demo, we have created the footer using the static block: https://ibb.co/Yc142wj and you have to go to Wp-Dashboard >> Static Block and edit that block with the page builder: https://ibb.co/FBRg49H and then change the footer logo as per your requirements: https://ibb.co/3CvnjKB
2. Upload your favicon in Theme Options > Site Identify https://prnt.sc/26931qk
Please read our theme documentation as well here: https://xstore.helpscoutdocs.com/article/64-how-to-add-custom-favicon
