STM32WLe5xx with STM32CubeWl (LoRaWAN) adding external Wakup from GPIO

[ESchu.3]

Hello,

for the STM32WLe5cc CPU with the STM32CUBEWL (LoRaWAN) i want also wakeup for sending a LORAWAN-package by GPIO (PA8).

The example: https://www.st.com/en/embedded-software/stm32cubewl.html

LORAWAN_END_NODE

I can configure the GPIO PA8 as GPIO_EXTI8 (STM32CubeIDE) and enable interrupt!

What must i change in the LORAWAN_END_NODE-example?

Greetings
