How is one supposed to use the trezord-udev-rules package? Can one just install it using guix install trezord-udev-rules, should it be added to packages in config.scm or should it be added to the udev service configuration?

I'm asking because I cannot actually test them (because I have no trezor) but want to make a similar package for Ledger devices since those udev rules are also published on GitHub.

Also does the user need to be added to any additional groups?
