Arduino Micro keyboard

Goodmorning everyone,

I'm developing a function keypad with Arduino Micro. I read 4 digital inputs and send F1, F2, F3, F4 to the PC via the Keyboard.h library.

Can I do so when I connect the keypad to a PC the keyboard is not recognized as an Arduino but only as a HID? In practice I won't install the Arduino the driver in the client PC.

Thank you
