How to launch Steam games with `gamemoderun`?

I'm trying to launch Ghost of Tsushima with HDR, but HDR just isn't recognized out of the box.

A comment on ProtonDB ( https://www.protondb.com/app/2215430/#i-0KizNc24 ) suggests changing the steam Launch Options to:

ENABLE_HDR_WSI=1 gamescope --fullscreen -w 3440 -h 1440 -r 144 --hdr-enabled --hdr-debug-force-output -- env ENABLE_GAMESCOPE_WSI=1 DXVK_HDR=1 DISABLE_HDR_WSI=1 gamemoderun %command%


But gamemoderun isn't available in the default KDE bazzite-nvidia:stable. Keeping gamemoderun in the command causes crashes at launch. I tried just scrubbing gamemoderun from the command which allowed GoT to start, but HDR remained unavailable.

What do I need to do to get gamemoderun available, or is there something else I can sub in for it?
