Unable to activate RTC interrupt in CubeMX for STM32L432KC

Hi Everyone,

after enabling RTC for the STM32L432KC in STM32CubeMX (version 6.18.0) RTC_WKUP_IRQn doesn't show up in the CubeMX NVIC panel for this MCU but is present in the vector table.

Is that a bug or am I missing something?

Best regards

 You need to activate Internal WakeUp first.
