So how about CPT’s

Okay nice plugin, but how am I going to use this for my CPT’s (Custom Post Types)?

At this moment, if I make a CPT it does not show the little box “Editor” where I can switch to the Gutenberg-editor. This “Editor” box is shown at pages and posts but not at CPT.

So how can I enable this box so that a WordPress user can use the Gutenberg editor on a CPT?

Thanks.
