Compilation error: 'ledcSetup' was not declared in this scope

I am trying to upgrade my cube from your first version and getting an error when I try to upload to the ESP32. I have made it through most of the issues I encountered but this one I am unable to resolve so hoping you can point me in the right direction.

My search led me to an upgrade thread for arduino ESP32 for migration from 2.0 - 3.0 that aligns with the timeline for your code release date so maybe that's it. I just don't know how to resolve it.

Yes, use ESP32 2.*.
