GoG mac releases have a new icon but the .app you replace it with has the old icon

"You should really only replace the binary in the MacOS folder instead of replacing the whole .app"

The issue mentions Mac .app bundles and icons. Look for the macOS application bundle structure in the repository, likely under a release or build directory. Check where the icon files (.icns) are stored and how the binary is packaged. Determine if the icon needs to be updated in the .app bundle or if the build process copies the wrong icon.
