Webflow CMS with Mapbox storytelling

I would like to know how to integrate this codeenter code here into the webflow service with the CMS option, because on webflow n (not allow codes that exceed 1000 characters. and as I need to make a story a bit long so I thought of using the CMS on webflow but it’s really beyond me because I’m not a programmer

I have not the code but I will try to put it here. but I have the site to clone from webflow if it can help you mapbox-scrollytelling - Webflow
