nrf sniffer menu does not exist.

[odenwar]

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?

It doesn't work even though I tried running the problem in Trouble Shooting 6.1.
