Channel Sounding : Pairing and Configuration

Hi,
I'm currently in architecture definition stage, and I'd like to know more about the possibilities driven by Channel Sounding.
From what I understand, you can only perform channel sounding when devices are connected.
I have uses cases where a lambda user could come and would like to pair with the device.
Uses cases lile indoor navigation for instance.
I do not want to pair only with one device, but with all devices.
what method of configuration would you recommend? 
Also, can Channel sounding be used to secure the pairing of a device? 
BR
