The last commit on that repository was 7 years ago, seems unmaintained. I wouldn’t recommend using this.
If someone decides to use it anyway, don’t use their udev rules. Just install steam-devices
or game-devices-udev
instead. If you don’t have those packages available in your distro, all rules can be found in the git repo https://codeberg.org/fabiscafe/game-devices-udev

A fix has already been published to Steam stable on Flathub. Workarounds can be removed now.
