sudo make install_fw is optional if your system (/lib/firmware/rtl_bt) has the firmware needed already.
ONLY kernel 5.15 ~ 6.6 are supported.
For kernel 6.6+ users, the built-in bluetooth driver in the kernel should work for you.
Tested with RTL8822BU/RTL8852BE on the following distros and it works fine.
Arch Linux (kernel version: 6.1.123-1-lts61)
Ubuntu 20.04 (kernel version: 5.15.0-124-generic)
