RAK2287 Chirpstack "Enable network geolocation"


I have a RAK2287 running Chirpstack. In my Service Profile I note that there is an “Enable network geolocation” tickbox. I’m keen to use this feature but I’m struggling to find any documentation on how to do so. For example, on this page:
it’s mentioned but not explained.

Can anyone point me in the right direction for some documentation (preferably beginner-friendly!)?

Many thanks

Maybe someone could point me to the code that runs if you do/don’t tick the “Enable netowrk geolocation” tickbox??
