React-Router とリンクして Props を渡すにはどうすればよいですか?

<Route name="ideas" path="/:testvalue" handler={CreateIdeaView} />

<Link to={{pathname: '/', query: {backUrl: 'theLinkData'}}} />

<Link to={{pathname: '/', search: '?backUrl=theLinkData'}} />

const CreatedIdeaView = () => {
  const { query, search } = useLocation();
  console.log(query.backUrl, new URLSearchParams(search).get('backUrl'));
};

class CreateIdeaView extends React.Component {
  render() {
    console.log(this.props.location.query.backUrl);
    return <div>{this.props.location.query.backUrl}</div>;
  }
}

class App extends React.Component {
  render() {
    return (
      <div>
        <Link to={{pathname: '/ideas', query: {foo: 'bar'}}} />
        <RouteHandler />
      </div>
    );
  }
}

class Ideas extends React.Component {
  render() {
    const { match, location } = this.props;
    console.log('props form link', this.props);
    return <p>{location.query.foo}</p>;
  }
}
