speaking of architectures... how does flatpak detects default target architecture?

my tablet kernel arch is x86_64, so i installed org.kde.mobile.angelfish/x86_64 and it works just fine, but navigation bar is blank.

angelfish log from tablet: https://gist.github.com/CODeRUS/f8dc...8897f4c54a1c85

then!

i opened xa2 which have aarch64 kernel, so i removed arm angelfish, and tried to install aarch64 one, but its not available
then i installed org.telegram.desktop/aarch64 but it's failing to start with syscall error: https://gist.github.com/CODeRUS/49bf...3f121229f3c02b
