I don’t believe anyone ever made one for Kleopatra. Maybe this will help. It’s for tails os, but I don’t see what it wouldn’t work on linux as well. Anyway, if you need to edit it, feel free to do so.
Instructions for using Kleopatra on Tails os.
Note – Should be mostly the same for Linux users except for the persistent storage
