Hello, @TFS,
1.. Simply go to the Dashboard >> Static Blocks >> the edit the Footer block with Elementor like as you see in the image: https://postimg.cc/4H1kmhRd you can edit/remove the content as per your need changes will appear on the site automatically.
2.. Actually, You have to build the footer just like you want, there is no option to import the footer of the “NICHE MARKET”
I hope you understand.
