FAQ schema missing in schema generator

I’d like to use the FAQ schema for a post without using RankMath’s FAQ block. According to this help page (and several others), the FAQ schema should be available in the free version, and several screenshots on that help page show the FAQ schema being available in the schema generator. However, I can’t see it anywhere:

I’ve noticed that the How-To schema is missing as well, though I don’t need it at the moment.

The AI chatbot on the help page tells me this:

Double-check that you have enabled the FAQ schema module in the Rank Math settings. To do this, go to your WordPress dashboard, navigate to Rank Math > Dashboard, and make sure the “FAQ” module is activated.

which seems to be wrong as there is no FAQ module, and I’ve never seen a mention of it anywhere else. I’d expect the FAQ schema to be part of the general Schema module anyway.

What could be causing this?
RankMath 1.0.120
WordPress 6.2.2
