Sending vst output to a group track

I want to send the output of 3 VST channels to a group track. I select the three tracks, right click, select ‘add track’ then select ‘group channel to selected channel’ and give it a group name. So the 3 vst outputs go though 1 group channel. This works fine, but I have no way to see which group any particular vst is routed to. With audio files, I cann see in the inspector window, but with VST tracks this isnt possible. How can I see what group a vst is routed to ?

Mixer?

How ?

what is that ? How do I see that ?
