How can I get the name of the clicked button?

I have several buttons on the screen.

All buttons have an “on click” Function. All buttons calling this function here: “ButtonClicked”.

Now, what I want to do is this here:

public void ButtonClicked() {

  if (buttonName == "save") {
   // ... do something
   }

   if (buttonName == "load") {
   // ... do something
   }

}

gameObject.name will give the GameObject name that the script is attached to.
