Sony A7R III focus tethering

Hi there, I am using capture one 20 pro build 13.1.4.3 On Windows with Sony A7r III.

When tethering liveview , on the  focus tab the button [AF] in the middle  is working fine but buttons  (near/far) << >> are greyed. Probably not working with my version. Has this been fixed in later versions like capture one 22 ? 

I want to know the specs for making my sony camera fully compatible for tethered working with capture one. So how to make that happened ?

Thanks in advance.
