After installing Pixelorama via Flatpak, the pixelorama command doesn't work.

I followed the standard installation method from Flathub, but when I tried to execute the command pixelorama, it didn't work. Even the .desktop file has no icon, and when I try to launch it, it says: "Could not find the program 'pixelorama'." The content of the .desktop file is:

```

Quick fix:
Copy the .desktop file to ~/.local/share/applications and replace:

`Exec=pixelorama`
with
`Exec=flatpak run com.orama_interactive.Pixelorama`

This allows me to run the program, but the icon is still missing.
