Facing problem opening flatpak apps

I downloaded Gaia sky app recently from flatpak since I couldn’t get the latest package through aur. All went fine and was able to install the Galaxies and Stars data easily but when I ran it, it lagged on my laptop. Here is the system info:

I have a dedicated trash GPU too and I want to test if it allows me to run the application a bit lagfree. All apps I wanted to run with that gpu could be run easily with DRI_PRIME=1 offload but gaia app just refuses to run and also freezes my desktop :slightly_frowning_face: . Is there any workaround for it. Any help will be appreciated :smiley:

Is there no way to run flatpak apps through other gpu. Or is there any way to install the Gaia app for manjaro with no access to latest versions through AUR
