Unable to run App Image Pool on Fedora Silverblue

[DaviMG07]

I tried running both the Flatpak and AppImage versions of the application, but it only displays a blank page.
I'm getting these errors:

** (appimagepool:4264): WARNING **: 18:02:02.085: Failed to start Flutter renderer: Unable to create a GL context

** (appimagepool:4264): WARNING **: 18:02:03.948: Unable to retrieve framework response: No engine to send to

** (appimagepool:4264): WARNING **: 18:02:03.972: Unable to retrieve framework response: No engine to send to

I saw a similar issue on flutter github here. Using Flatseal, I exported the variable export LIBGL_ALWAYS_SOFTWARE=1. At least it shows the application now, but it's still not running as expected.

A comparison between how flatseal and appimagepool are being displayed. the app doesn't follow the desktop theme, nor the size:

Running from terminal I got that:
