Some function keys of MacBook cannot be detected

[werifu]

I'm using MacBook Pro (M1 Pro 2021)

My keyboard is like the picture below:

When I'm running the example cargo run --example listen, I found some some function keys does not be detected by listen(callback), what I mean is that the nothing happened when I pressed F1, F2, F7, F8, F9, F10, F11, F12. Only F3~F6 can be listened, but they would be handled as Unknown event types. ( I edited the code in listen.rs only to print KeyPress event )
