Stm32L4 doesn't wakeup from shutdown

I'm using mbed coding on stm32L432kc nucleo board. I'm copying the code from the stm32 cube code examples to put my MCU in shutdown [https://github.com/Rayling35/STM32Cube_FW_L4_V1.12.0/blob/master/Projects/NUCLEO-L432KC/Examples/PWR/PWR_SHUTDOWN/Src/main.c]

The code compiles fine. I just added an LED blink inside the while (1) loop after the shutdown command to see if the MCU has wakeup up but it never blinks.

Any idea what I'm doing wrong?
