I would be glad to test it on SteamOS, but I do not have a Steam Deck.
Used and tested on desktop with Steam in -steamdeck mode with gamescope

@allmazz Since this is a new plugin, please recruit a tester in our Discord server or elsewhere who can install and test this plugin on a Steam Deck. That is our primary userbase and any plugins on the store should generally work on Steam Decks unless very clearly intended for other devices.

[EMERALD0874]

Sorry, I misremembered our requirements. It doesn't need to be tested on a Steam Deck, but you do need to test it on SteamOS in general. Please do that and we can move forward with the PR process! :)

Confirming that this works on the Deck

Code LGTM, just want a confirmation that the dependencies you mentioned needing (wpctl and pw-dump) are present on a stock Steam Deck, we don't want plugins that require users disabling read-only or otherwise modifying the system.

If you can confirm that those packages exist on a stock install then I'll get it off to testing.

Yes, they preinstalled since SteamOS uses pipewire with wireplumber and in Arch there is no separate package pipewire-tools like on Fedora. Kindly confirmed and tested by a discord server member.
