Ok, If I get it right, you didn’t create first pop-up. Then, probably you could copy it, change there all what you need (add information or delete) and link it to the specific span in the footer.
Without read only link to your site I can’t help more, sorry.
How to share your site in “read only” mode you can see here How to Enable a Webflow Share Link - Webflow Tips - Forum | Webflow
