X-CUBE-USB-AUDIO compatibility with STM32G4 USB peripheral

[Franz.1]

Can anyone tell whether the USB audio streaming extension is supposed to be compatible with the USB peripheral of STM32G4?

It is clear that the application part of the extension has to be ported, but is the extension supposed to work without modification of the core files of the extension - e.g. the MACROS defined in the hal_usb_ex.h ?
