Gateway location not updated automatically

Hello,

I have Gateway running Chirpstack GW os and ChirpStack Version: v4.11.1.
When I move my gateway to another location I need to manually drag the pin on the UI map.

I understand that GW should send periodic stats messages (which I assume will contain location data as per this article Gateway management - ChirpStack open-source LoRaWAN® Network Server documentation), but I do not see the option to enable it in Version: v4.11.1. I remember it was there in older ChirpStack versions.

Another question: how GW can aquire location? In my case, I am using RakWireless concentrator which has GPS, but I doubt it is automatically talking with the host (RPI) and sharing the Lat,Long.

Is it enough to have GPS on the concentrator module? Or I should have GPS attached to the host as well (via UART f.eg)?

Could someone explain how this process works?

Thanks
