Can no longer user 3rd-party survey link

So from the docs there used to be an option to use 3rd party surveys:
https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0067657 (under step 6)

But since Zoom implemented their own surveys, it looks to me like you guys quietly gutted this feature. Is this feature still available? If not, maybe update your docs so there's no confusion.
