React:如何在任何导航上运行函数？

import React from 'react';
import { BrowserRouter as Router, Link, Route } from 'react-router-dom';

const Home = () => {
  const handleClick = () => {
    // 在这里编写你想要运行的函数
    console.log('运行函数');
  };

  return (
    <div>
      <h1>首页</h1>
      <button onClick={handleClick}>运行函数</button>
    </div>
  );
};

const About = () => {
  return <h1>关于</h1>;
};

const App = () => {
  return (
    <Router>
      <div>
        <nav>
          <ul>
            <li>
              <Link to="/">首页</Link>
            </li>
            <li>
              <Link to="/about">关于</Link>
            </li>
          </ul>
        </nav>

        <Route path="/" exact component={Home} />
        <Route path="/about" component={About} />
      </div>
    </Router>
  );
};

export default App;
