How to set up Nitrokey 3 with KeepassXC on (K)Ubuntu

It’s not a solution for Qubes.

Is there a command needed to mnt the Nitrokey because I started KeePassXC after I had the USB key attached to the VM (vault) and “Hardware Key” says “No Hardware Keys Detected.”

But Nitro LED flashes when refresh button is pushed so there is software/hardware interaction.
