Hotone and quad cortex

Kindly show or explain how to effectively install the hotone cory press onto the qc

I am having problems expression 1 is connected and calibrated however I connected expression 2 to the second output the cory press but it is not calibrating

My objective is to use the cory press as a volume and a wah pedal using the feature of the switch to toggle between both the volume and the wah

I look forward to your positive and detailed assistance

Thank you
