React -如何根据API-result显示propup？

import React, { Component } from 'react';

class Popup extends Component {
  render() {
    const { result } = this.props;
    
    return (
      <div>
        <h2>API Result:</h2>
        <p>{result}</p>
      </div>
    );
  }
}

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      apiResult: null
    };
  }

  componentDidMount() {
    // 发送API请求，并将结果保存到state中
    fetch('https://api.example.com/data')
      .then(response => response.json())
      .then(data => {
        this.setState({ apiResult: data });
      });
  }

  render() {
    const { apiResult } = this.state;

    return (
      <div>
        {apiResult && <Popup result={apiResult} />}
      </div>
    );
  }
}

export default App;
