请教一下通过什么方式可以调用@ohos.wifiManager被隐藏的wifiManager.getDeviceMacAddress()函数来获取MAC地址

如题：请教一下专家，

通过什么方式可以调用@ohos.wifiManager被隐藏的wifiManager.getDeviceMacAddress()函数来获取MAC地址；

C:\Program Files\Huawei\DevEcoStudio507\sdk\default\openharmony\ets\api\@ohos.wifimanager.d.ts里getDeviceMacAddress()函数被隐藏了，

但是框架层是支持这个函数的，在interface/sdk-js/api/@ohos.wifimanager.d.ts里有该函数的定义，但是拷贝替换过去以后，dev-eco仍然不识别；提示以下编译错误：

有什么步骤操作能使用到这个函数或其它正规途径来获取OpenHarmony5.0下的WiFi MAC啊？

1.你这是any类型

要改一下

let mac: string[] = wifiManager.getDeviceMacAddress();
2.

import wifiManager from '@ohos.wifiManager';
在@ohos.wifiManager中有getDeviceMacAddress不？需要full's'd'k
