Chromium Flatpak "app" mode won't use dGPU

question

I'm trying to get Geoguessr to use my dGPU, because I've found it can be a bit slow on the iGPU. However, no matter what I try, I can't seem to get it to work. I have GPU Acceleration turned on with Flatseal, I have Wayland enabled with X11 fallback, and this is my desktop file. It has

PrefersNonDefaultGPU=true

PrefersNonDefaultGPU=true

.

I've checked other flatpak applications, and they work with the dGPU just fine. For some reason, it's just this one that's not working.
