Kindle Voyage/Ubuntu 20.04: mount "not authorized"

I am trying to get my Kindle Voyage recognized by calibre. I am seeing this error:

It looks like some sort of permissions error when Calibre tries to mount the device, but I'm puzzled where to look to sort this out.

No clue you will need to ask in your distros forums for how to get udisks working with your user account. Or jsu tmount the kindle yourself before starting calibre.
