如何将全屏事件添加到Highchart？

<script src="https://code.highcharts.com/highcharts.js"></script>

<div id="chartContainer"></div>

Highcharts.chart('chartContainer', {
   // 图表的配置选项
});

Highcharts.chart('chartContainer', {
   // 图表的配置选项
   
   chart: {
      events: {
         load: function() {
            var chart = this;
            
            // 创建全屏按钮
            chart.fullscreenButton = chart.renderer.button('全屏', null, null, null, null, null, null, null, 'fullscreen-button')
               .attr({
                  align: 'right',
                  title: '全屏'
               })
               .on('click', function() {
                  chart.fullscreen = !chart.fullscreen;
                  chart.setSize(null, null, chart.fullscreen);
               })
               .add();
         }
      }
   }
});
