I have a problem with react-router-dom and Prompt. The problem is Prompt' (imported as 'Prompt') was not found. Has something changed in the new versions?

Here is my code:

import React from 'react';
import '../styles/ContactPage.css';
import { Prompt } from 'react-router-dom';

class ContactPage extends React.Component {
    state = {
        value: ''
    }
    handleSubmit = e => {
        e.preventDefault();
        this.setState({
            value: '',
        })
    }
    handleChange = e => {
        this.setState({
            value: e.target.value,
        })
    }

    render() {
        return (
            <div className='contact'>
                <form>
                    <h3>Send a form</h3>
                    <textarea value={this.state.value} onChange={this.handleChange} placeholder='write something'></textarea>
                    <button onSubmit={this.handleSubmit}>Send</button>
                </form>
                <Prompt when={true} message={"You did not end your form. Are you sure you want to change a page? All data will be lost"} />
            </div>
        );
    }
}

export default ContactPage;
