React react-bootstrap -如何从外部组件关闭模式窗口

import React, { useState } from 'react';
import { Button, Modal } from 'react-bootstrap';

function ParentComponent() {
  const [showModal, setShowModal] = useState(false);

  const handleCloseModal = () => {
    setShowModal(false);
  };

  const handleShowModal = () => {
    setShowModal(true);
  };

  return (
    <>
      <Button variant="primary" onClick={handleShowModal}>
        打开模态窗口
      </Button>

      <Modal show={showModal} onHide={handleCloseModal}>
        <Modal.Header closeButton>
          <Modal.Title>模态窗口标题</Modal.Title>
        </Modal.Header>
        <Modal.Body>模态窗口内容</Modal.Body>
        <Modal.Footer>
          <Button variant="secondary" onClick={handleCloseModal}>
            关闭
          </Button>
          <Button variant="primary" onClick={handleCloseModal}>
            保存
          </Button>
        </Modal.Footer>
      </Modal>
    </>
  );
}

export default ParentComponent;
