macOS specific keycodes does not work as expected

[mr2rm]

I added the following keymaps on Kinesis Advantage 360 Pro to enable Application Controls available on the MacBook keyboard and I used a keymap editor to do so. But, I couldn't see any events detected in Karabinar related to those keys, and they don't work as expected.

Keymaps:

• &kp C_AC_SEARCH: Toggle Spotlight search - {"key_code": "f4"}
• &kp C_AC_DESKTOP_SHOW_ALL_WINDOWS: Show all the windows, - {"key_code": "f3"}
• &kp C_AC_DESKTOP_SHOW_ALL_APPLICATIONS: Show all applications?
• &kp C_AC_NEXT_KEYBOARD_LAYOUT_SELECT: Select the next keyboard layout (Apple Globe) - {"apple_vendoer_top_case_key_code": "keyboard_fn"}

Also, here are my changes for creating a custom firmware that I used: mr2rm/Adv360-Pro-ZMK@9cb9ddb
