Control Allowed Editor Missing? | WordPress.org

We just installed Publishpress Capabilities after reading https://publishpress.com/blog/gutenberg/disable-gutenberg-block-editor/#Option_3_Disable_Gutenberg_for_some_roles_and_post_types.

We manage a client site for SEO. We disable Gutenberg on all our client sites, because we hate it. Our client wishes to have it enabled only for PAGES so he can edit them – we don’t touch those.

So in following the guide here, we tried to access the “Control Allowed Editor” referenced here, but it does not exist.

Help?
