如何访问包装在React-Redux的connect函数中的functional子组件中的ref？

const MyComponent = React.forwardRef((props, ref) => {
  // 子组件的逻辑和渲染
  return <div ref={ref}>子组件内容</div>;
});

import { connect } from 'react-redux';

const mapStateToProps = (state) => {
  // mapStateToProps的逻辑
};

const mapDispatchToProps = (dispatch) => {
  // mapDispatchToProps的逻辑
};

const MyConnectedComponent = connect(
  mapStateToProps,
  mapDispatchToProps
)(React.forwardRef((props, ref) => {
  // 子组件的逻辑和渲染
  return <div ref={ref}>子组件内容</div>;
}));

class ParentComponent extends React.Component {
  constructor(props) {
    super(props);
    this.childRef = React.createRef();
  }

  componentDidMount() {
    // 访问子组件中的DOM元素
    console.log(this.childRef.current);
  }

  render() {
    return <MyConnectedComponent ref={this.childRef} />;
  }
}
