 if (completed) {
  return <span>00:00</span>;
 } else {
  return <span>{minutes}:{seconds}</span>;
 }
}

export default function Timers() {
  return <Countdown date={Date.now() + 70000} renderer={timerRenderer} />
}

4. The dev tools display the following error:

The issue here seems to relate to a similar one as we're faced with when importing react itself, prop-types only exports CJS/UMD and has no ESM build.
