如何在react ts中对单个onClick上的多个按钮进行计数？

import React, { Component } from 'react';

class ButtonCounter extends Component {
  constructor(props) {
    super(props);
    this.state = {
      count: 0,
    };
  }

  handleClick = () => {
    this.setState(prevState => ({
      count: prevState.count + 1,
    }));
  }

  render() {
    return (
      <div>
        <button onClick={this.handleClick}>按钮1</button>
        <button onClick={this.handleClick}>按钮2</button>
        <button onClick={this.handleClick}>按钮3</button>
        <span>点击次数：{this.state.count}</span>
      </div>
    );
  }
}

export default ButtonCounter;
