Rpm-ostree install of libratbag does not install dependencies

Steps to reproduce:
rpm-ostree install libratbag-ratbagd
ratbagctl list

Traceback (most recent call last):
File “/usr/bin/ratbagctl”, line 26, in
import evdev
ModuleNotFondError: No module named ‘evdev’

At a glance this seems to be a bug in the package itself, python3-evdev is listed in BuildRequires but not Requires. Please file a bug for the package.

Did you have any luck getting the Flatpak to run? Been trying to install this to configure my Logitech mouse.

$ flatpak run org.freedesktop.Piper                                                                                                                         1 ↵  18:10:19

To be honest I gave up and used ratbagctl on the command line to set my led hex code.
