Google Maps Custom Info Windows - откройте одно, а затем закройте другое, как только оно откроется

Question

Я борюсь с этим - Получил карту Google с некоторыми пользовательскими окнами информации. Таким образом, при нажатии на маркер изменится информация на поле слева. Получил значение по умолчанию, отображаемое при загрузке на странице, и его нужно изменить, когда вы щелкнете по разным точкам на карте. У меня меняется Франция, но вы не можете нажать на другие пункты. Аналогично с Нью-Йорком. Любые идеи, где я иду не так?

Я приложил ниже мой код. Любая помощь будет высоко ценится.

Надеюсь, что помогает.

function initialize() {

  var mapOptions = {
    center: {
      lat: 40.7499256,
      lng: -73.9854028
    },
    zoom: 3,
    zoomControl: false,
    panControl: false,
    streetViewControl: false
  };

  var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

  var img = "https://i.stack.imgur.com/JWM0W.png";

  var NewYork = new google.maps.Marker({
    position: mapOptions.center,
    map: map,
    icon: img
  });

  var London = new google.maps.Marker({
    position: {
      lat: 51.5106122,
      lng: -0.1529072
    },
    map: map,
    icon: img
  });

  var Paris = new google.maps.Marker({
    position: {
      lat: 48.8588589,
      lng: 2.3470599
    },
    map: map,
    icon: img
  });

  var HongKong = new google.maps.Marker({
    position: {
      lat: 22.2753729,
      lng: 114.1757384
    },
    map: map,
    icon: img
  });

  var markers = {
    'NewYork': NewYork,
    'London': London,
    'Paris': Paris,
    'HongKong': HongKong
  };

  NewYork.addListener('click', changeContent);
  Paris.addListener('click', changeContentTwo);
