我正在使用 GrapesJS 模板编辑器开发一个项目，并且尝试使用两个按钮实现撤消/重做功能。当然，我创建的按钮目前没有撤消和重做操作。
请帮我！
<div class="action">
<a class="btn" id="undo-btn"><i class="fa fa-undo"></i></a>
<a class="btn" id="redo-btn"><i class="fa fa-redo"></i></a>
</div>
const editor = grapesjs.init({
// Indicate where to init the editor. You can also pass an HTMLElement
container: '#gjs',
// Get the content for the canvas directly from the element
// As an alternative we could use: `components: '<h1>Hello World Component!</h1>'`,
fromElement: true,
// Size of the editor
height: '300px',
width: 'auto',
// Disable the storage manager for the moment
storageManager: false,
// Avoid any default panel
panels: { defaults: [...] },
// ...
});
$('#undo-btn').click(function() {
// undo action here
})
$('#redo-btn').click(function() {
// redo action here
})
