Keychron keyboards on Linux + Bluetooth fixes

Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.

Note: many newer Keychron keyboards use QMK as firmware and most tips here do not apply to them. Maybe the ones related to Bluetooth can be useful, but everything related to Apple's keyboard module (hid_apple) on Linux, won't work. As far as I know, all QMK-based boards use the hid_generic module instead. Examples of QMK-based boards are: Q, Q-Pro, V, K-Pro, etc.

Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.

Make Fn + F-keys work (NOT FOR QMK-BASED BOARDS)

Older Keychron keyboards (those not based on QMK) use the hid_apple driver on Linux, even in the Windows/Android mode, both in Bluetooth and Wired modes.

Just another reason to why you shouldn't use Lombok, in another saying another reason to why you should write unit tests: You have two fields in your class. Fields are in the same type. You use @AllArgsConstructor to auto-generate your all args constructor. It works for a moment, until you change the order of the field.
import lombok.AllArgsConstructor;
import lombok.Data;
@Data
@AllArgsConstructor
public class LazyDeveloper {
private String firstName;
private String lastName;
