How do I set the Cubase Pitch correction plugin to follow chord track scale?

How do I set the Cubase Pitch correction plugin, to follow chord track scale?
I selected the option, but it’s not correcting. I know how to make it follow midi track and define my own scale, am I missing something setup wise? should it not display the scale? somewhere ? scale that is displayed on chord track?

oh WOW! never mind, I have to create a midi track that feeds to Pitch Correction VST and that MIDI track is getting input from chord track… this is very odd routing.
