Example via CubeIDE is OK, but same via MX is not (STM32C0, Ux_Host_HID_Standalone)

This appears to be loosely related to

If I start with Cube IDE:

File -> New -> STM32 Project then select NUCLEO-C071RB and then Ux_Host_HID_Standalone

all goes swimmingly well.  However, if I start with CubeMX, then choose the same example I get errors:

I can make the Platform Settings error go away by assigning a GPIO to who knows what, per the related post, but I don't want to waste a GPIO and furthermore, I want to make changes to the project that I cannot do using the IDE-only method. Is there some other setting I'm missing in the CubeMX example creation?

My best guess at the moment is that the CubeMX generated version requires the dummy GPIO for

void USBH_DriverVBUS(uint8_t state);

found in usbxh_platform.c .h

I don't see this function being called anywhere though.
