How to add `onscroll` event in ReactJS component

App.js

import React from 'react';

let lastScrollY = 0;
let ticking = false;

class App extends React.Component {
  componentDidMount() {
    window.addEventListener('scroll', this.handleScroll, true);
  }

  componentWillUnmount() {
    window.removeEventListener('scroll', this.handleScroll);
  }
    
  nav = React.createRef();
  
  handleScroll = () => {
    lastScrollY = window.scrollY;

    if (!ticking) {
      window.requestAnimationFrame(() => {
        this.nav.current.style.top = `${lastScrollY}px`;
        ticking = false;
      });
   
      ticking = true;
    }
  };

  render() {
    return (
      <div>
        <nav ref={this.nav}>
        </nav>
      <div>
    );
  }
}

export default App;
