Access to drafts via iCloud Drive on the Mac

See title. Is this possible? I don’t see Drafts as an option to enable in my Mac’s iCloud drive settings. I have enabled iCloud sync in the Drafts 5 iOS app. Thanks.

There is more detail on sync in the docs, but short story is that Drafts does not sync using files. It sync using CloudKit, the same underlying technology as iCloud Drive (and Notes sync, etc.). You can export to iCloud Drive files, but it is not part of sync.
