[tvOS][XCTest] Detect which keyboard key has focus

I am writing a UI automation test for a view on Apple TV. The view has a numeric input field(TVDigitEntryViewController) which accepts 5 digits password. When the view loads the focus is on key '1' of the numeric apple input keyboard for tvOS. However when I try po pinEntryKeyboard.keys["1"].hasFocus in the debug terminal it says false. Is there a way to find out which keyboard key has focus for tvOS input keyboard?

For more context I am adding some debug terminal output here:

(lldb) po pinEntryKeyboard.keys
