Clion Python PySide2... no code insights/autocomplete ?

Hey

I've just added a venc python to my c++ project, I installed PySide2 using python Interpreter tab in settings & enabled Compatibility mode with PySide2. However when I type something like:

w = QWidget() / w.show() and try pressing ctrl+w.show() click I get no follow up/insights/auto complete etc etc

How can I get the python to properly use IDE?

TIA
