How to use interworking_select command within wpa_cli utility?

[work vlpl]

Hello,
I am testing hotspot 2.0 functionality, and can't figure out how to
use interworking_select command  within wpa_cli  utility.

I run hs20 test from hwsim directory, pause test with pdb.set_trace(),
to get device in desired state and do my other work.

interworking_select command that start from python code works
perfectly, for example this is output from wpa_cli

...

...

But if I try run it manually from wpa_cli (wlan0 and wlan3 still
desired configured state because hwsim tests in pause), utility return
this

> interworking_select
Unknown command 'interworking_select'
> set interworking 1
OK
> set hs20 1
OK
> interworking_select
Unknown command 'interworking_select'

What should I do to make `interworking_select` command work?
