如何移除Google Maps的位置框(左上角)？

var mapOptions = {
  disableDefaultUI: true
};
var map = new google.maps.Map(document.getElementById('map'), mapOptions);

var customControlDiv = document.createElement('div');
var customControl = new CustomControl(customControlDiv, map);

customControlDiv.index = 1;
map.controls[google.maps.ControlPosition.TOP_RIGHT].push(customControlDiv);

function CustomControl(controlDiv, map) {
  // 创建自定义控件的HTML元素
  var controlUI = document.createElement('div');
  controlUI.style.backgroundColor = 'white';
  controlUI.style.border = '1px solid gray';
  controlUI.style.borderRadius = '3px';
  controlUI.style.boxShadow = '0 2px 6px rgba(0,0,0,.3)';
  controlUI.style.cursor = 'pointer';
  controlUI.style.marginTop = '10px';
  controlUI.style.marginRight = '10px';
  controlUI.style.textAlign = 'center';
  controlUI.title = 'Click to remove location box';
  controlDiv.appendChild(controlUI);

  // 添加控件的文本内容
  var controlText = document.createElement('div');
  controlText.style.color = 'rgb(25,25,25)';
  controlText.style.fontFamily = 'Roboto,Arial,sans-serif';
  controlText.style.fontSize = '14px';
  controlText.style.lineHeight = '30px';
  controlText.style.paddingLeft = '5px';
  controlText.style.paddingRight = '5px';
  controlText.innerHTML = 'Remove Location Box';
  controlUI.appendChild(controlText);

  // 添加控件的点击事件
  controlUI.addEventListener('click', function() {
    // 移除位置框
    // ...
  });
}
