如何从leaflet control-layers-toggle更改标签？

var map = L.map('map');

var baseLayers = {
  "地图": L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
    attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/">OpenStreetMap</a> contributors'
  }),
  "卫星图": L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
    attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/">OpenStreetMap</a> contributors'
  })
};

var overlayLayers = {
  "标记": L.marker([51.5, -0.09]).addTo(map)
};

var controlLayers = L.control.layers(baseLayers, overlayLayers).addTo(map);

var toggleControl = controlLayers.getContainer().getElementsByClassName('leaflet-control-layers-toggle')[0];
toggleControl.innerHTML = '新的标签内容';
