Hello,
If you want to actually connect to the hardware event, that may not be easy at all, otherwise this might be useful.

Hi,

Do you mean you would like to do something when it's shutting down i.e. save the state of your application ? Or react on the button itself ?

What do you need it to do ? Save the state of your application ? Block the shutdown ?
