如何在React JS中配置Ckeditor Toolbar？

import React, { Component } from 'react';
import CKEditor from '@ckeditor/ckeditor5-react';
import ClassicEditor from '@ckeditor/ckeditor5-build-classic';

class MyEditor extends Component {
  render() {
    return (
      <div>
        <h2>My CKEditor</h2>
        <CKEditor
          editor={ ClassicEditor }
          data="<p>Hello from CKEditor!</p>"
          onInit={ editor => {
            // You can customize the toolbar here
            editor.ui.getEditableElement().parentElement.insertBefore(
              editor.ui.view.toolbar.element,
              editor.ui.getEditableElement()
            );
          } }
          onChange={ ( event, editor ) => {
            const data = editor.getData();
            console.log( { event, editor, data } );
          } }
        />
      </div>
    );
  }
}

export default MyEditor;
