How can I know the GPIO_Typedef of a Pin?

I connected a LED to the PA11 pin of STM32WB55VGY microcontroller

and I want to toggle it.

So, I'm trying to use HAL_GPIO_TogglePin(xx, yy) but I cannot know the "xx (GPIO_Typedef)" of PA11 pin.

Where can I found which pin is which GPIOx?

It is GPIOA :)

GPIO_Typedef of pin PB11 is GPIOB. ...

The pin associativity would be in the Data Sheet.

HAL_GPIO_TogglePin(GPIOA,GPIO_PIN_11);.
