如何在openlayers中实现绘制交互的重做？

// 创建地图容器
var map = new ol.Map({
  target: 'map-container',
  layers: [
    // 添加地图图层
    new ol.layer.Tile({
      source: new ol.source.OSM()
    })
  ],
  view: new ol.View({
    center: [0, 0],
    zoom: 2
  })
});

// 创建绘制交互对象
var drawInteraction = new ol.interaction.Draw({
  type: 'Point',
  // 设置绘制样式
  style: new ol.style.Style({
    image: new ol.style.Circle({
      radius: 6,
      fill: new ol.style.Fill({
        color: 'red'
      }),
      stroke: new ol.style.Stroke({
        color: 'white',
        width: 2
      })
    })
  })
});

// 添加绘制交互到地图
map.addInteraction(drawInteraction);

// 撤销按钮点击事件
document.getElementById('undo-button').addEventListener('click', function() {
  drawInteraction.removeLastPoint();
});

// 重做按钮点击事件
document.getElementById('redo-button').addEventListener('click', function() {
  drawInteraction.addPoint();
});
