CMC-QC learn function not working with third party plugins MAC

Hi I am unable to use the Steinberg CMC-QC learn function to quickly assign and control third party plug-in parameters.
Everything else works. Works fine with all the Steinberg plug-ins. But with none of the third party ones. Can anybody help me figure this out?

Update - I found that I can assign the Quick Controls in the plugin Remote Control section, but it would be better if it was possible in the plugin GUI. Any solution?

Mac OSX 10.11.6
Cubase 9.5
