If you use a ref, do not forget to use tabIndex={x} to make the component focusable.

import { useRef } from 'react'
import useKeys from 'react-piano-keys'

function MyComponent() {
  const divRef = useRef()

  useKeys(divRef.current, 'up up down down left right left right b a', () => console.log('konami code!'))

  return (
    <div ref={divRef} tabIndex={0}>
      What could the code be?
    </div>
  )
}
