The approach I'd recommend here is different, because Code Export is a feature of the Workspace Plans, and NOT the Site Plans.
Again, confusing for many. But Webflow's position on this does make sense if you think about it.
Obviously, look into the details for yourself;
What happens if I cancel my Workspace Plan, and then later I want to re-activate it... will my FREE-plan Site still have more than 2 static pages, my CMS Items, my custom code, etc.?
I have no idea, but I wouldn't hold my breath.
Let me know if you find out.
