如何在ckeditor4-react中添加自定义插件？

npm install ckeditor4-react

CKEDITOR.plugins.add('customPlugin', {
    icons: 'customIcon',
    init: function(editor) {
        editor.addCommand('customCommand', {
            exec: function(editor) {
                // 在这里定义按钮点击后的操作
                alert('自定义插件按钮被点击了！');
            }
        });

        editor.ui.addButton('CustomButton', {
            label: '自定义按钮',
            command: 'customCommand',
            toolbar: 'insert'
        });
    }
});

import React from 'react';
import CKEditor from 'ckeditor4-react';

const CustomEditor = () => {
    const editorConfig = {
        extraPlugins: 'customPlugin'
    };

    return (
        <CKEditor
            config={editorConfig}
            data="<p>这是一个CKEditor示例</p>"
        />
    );
};

export default CustomEditor;
