nrf sniffer menu does not exist.

I have referenced the following document.

https://www.nordicsemi.com/-/media/DocLib/Other/User_Guides/nRFSnifferUGv22.pdf?la=en

I checked the contents up to 2.3.

However, I can't see the contents of 2.3.1.

What did I do wrong?

I'll ask you one more thing.
We are developing with one nrf52-DK product.
I want to develop ADC-BLUETOOTH, but this product is used for Bluetooth protocol detection, and is it correct that I need one more board for ADC - BLUETOOTH development?
