I'm on the free plan of Webstudio, so I can't use the CMS functionality directly. According to the documentation, I should be able to self-host a CMS site from Webstudio, but whenever I try to create a resource request, it just doesn’t save.

Am I missing something here? It seems like, to self-host with CMS, I'd need to build it in the builder—but the builder itself won’t let me use the CMS on the free plan.
