how to call direct parent's function by child?

I have three components: ComponentA, ComponentB and Home (Home is the component parent). I want to call a function contains in ComponentA using a button that is inside of ComponentB.

const ComponentA= () => {
  const hello=()=>{
    console.log("hello");
  }
  return <></>
})

const ComponentB= () => {
  const callComponentAFunction=()=>{
   // I need call "hello()" from ComponentA
  }
  return 
   <>
    <button onClick={callComponentAFunction}>Call function from ComponentA</button>
   </>
})

const Home= () => {
 return 
  (<>
   <ComponentA>
     <ComponentB />
   </ComponentA>
   </>)
 })

How can I call hello() function (inside of ComponentA) from ComponentB?
