How to configuring STM32MP157 GPIO as external interrupt for the M4 core using CubeMX?

[HAlzo]

I am trying to configure some HW IP to work with the M4 core of the STM32MP157, I can find only the GPIO already assigned to other IPs ont he development Kit.

How to configure GPIO's and configure interrupts related to SPI DMA from the M4 side?

Attached is a screenshot for the available GPIO's on CubeMX.
