When I recently tried to write a Gazell project using the nRF Connect SDK, I found that many files referenced the `nrf_gzll.h` file, but I did not find it in the nRF Connect SDK directory. Can you tell me where it is or how it was created?
For example, in `\sdk-nrf-main\samples\gazell\gzp_dynamic_pairing_device\src\main.c`:
