有没有办法在外部启用/禁用SunEditor上的保存按钮？

<textarea id="myEditor"></textarea>

const editor = SUNEDITOR.create('myEditor', {
  buttonList: [
    ['undo', 'redo'],
    ['bold', 'underline', 'italic', 'strike', 'subscript', 'superscript'],
    ['fontColor', 'hiliteColor', 'removeFormat'],
    ['outdent', 'indent'],
    ['align', 'horizontalRule', 'list', 'table'],
    ['link', 'image', 'video'],
    ['fullScreen', 'showBlocks', 'codeView'],
    // 移除保存按钮
    // ['save']
  ]
});

editor.onKeyDown = function (e, core) {
  if (core.isEmpty()) {
    editor.disabled('save');
  } else {
    editor.enabled('save');
  }
};
