STM32CubeMX is missing MCO and MCO2 on H7A3

STM32CubeMX is V5.5.0, but I suppose device definitions have different version numbers.

What package? I can find RCC_MCO_1 and RCC_MCO_2 on PA8 and PC0.

If you select Master Clock Output 1 & 2 in RCC configuration category, they should be selected on the pinout view.
