Kobo Plus (subscr.) DeDRM conversion possible?

Hi all,

I'm new, so please be gentle with me. :)

I am using Calibre 4.2.3, and have installed both tools in DeDRM Tools 6.8.1

When I saw this:

Release: 4.23 [21 Aug, 2020]
New features

Kobo driver: Add support for new firmware. Also add recognition of 'Kobo Plus' subscription books

I thought that I would be able to grab (and make local DRM-free copies of) books from a Kobo Plus subscription, perhaps in conjunction with the Obok DeDRM plugin. But so far, DRM remains on most books I've tried (the only ones I could read were some free ebooks from Kobo and one Kobo Plus book from a small publisher that maybe didn't have any DRM to start with).

Is there a way to convert most Kobo Plus books using Calibre (along with DeDRM?) so that they are readable?
