How to pass data from child component to parent?

Question

React

There is a Parent component :

function Parent() {
  const [state, setState] = useState([])

  return (
   <Buttons />
  )
}

And child Buttons :

function Buttons() {
  return (
   <Button>1</Button>
   <Button>2</Button>
  )
}

How to change the state of the parent ( Parent ) by clicking on the buttons of the Buttons component ?
