Button interrupt for WBA55CG

Hi community,

 

I'm having struggles with EXTI in WBA55CG. I want to implement a function, when the button is clicked, a message is sent via BLE. I have found the stm32wbaxx_hal_exti.c file. Can I follow exactly the same as the instructions or what i add more?

 

Thank you.
