ACF Google Map-更改样式？

我已经启动并运行了Wordpress网站，并使用ACF插件创建了Google Map字段。太好了，但是我想更改默认的Google地图样式。我的站点地图需要更浅的灰度样式。我使用了ACF文档中的以下代码，正如我所说的，它可以很好地工作，但是当我尝试更改任何样式时，都不会发生。我必须指出我不是精通javascript / jquery，因此请考虑一下。我确实浏览了整个Google Map API文档，但我做不到。我尝试了一堆东西，或者什么也没有发生，或者我丢掉了Google地图。因此，有人可以为我指出正确的方向，还是给我提供示例代码并说明在何处使用它。我应该删除现有代码的一部分，还是仅添加额外的代码等？在此先感谢您，并祝一切顺利！
