add to footer in child theme Hueman

I’d like to add more links and text in the main footer, rather than the extra widget footer facility which takes up huge space above this bottom black footer. I can find where and how to alter the credit and add social icons and a logo, but don’t seem to be allowed to do anything else. I’ve tried swapping to Nimble editor but its header and footer tab seems to change the whole page, individual or site wide.
Any help would be most appreciated.
