STM32 H5 Nucleo USB Custom HID
I'm trying to experiment with a Custom HID USB demo.
I'm following the instructions at:
How to implement a USB device custom HID class on ... - STMicroelectronics Community
Part way down it suggests:

However when I got to Middleware I don't have USB_DEVICE (I just have USBX)

I can't see a way to add the USB_DEVICE Package to to the middleware list.
Help (please)?
