HarmonyOS API12操作相册报权限问题？

Question

photoAccessHelper getPhotoAccessHelper inner add createDeleteRequest and showAssetsCreationDialog
createAsset failed, message =  Error: without medialibrary permission

代码如下：

requestPermissionsFn() {
  try {
    const atManager = abilityAccessCtrl.createAtManager()
    //申请相册管理模块权限'ohos.permission.WRITE_IMAGEVIDEO'
    atManager.requestPermissionsFromUser(appContext, [
      'ohos.permission.WRITE_IMAGEVIDEO', 'ohos.permission.READ_IMAGEVIDEO'
    ]).then(async () => {
      console.log(`request Permissions success!`);
      try {
        //获取相册管理模块的实例，用于访问和修改相册中的媒体文件
        let phAccessHelper = photoAccessHelper.getPhotoAccessHelper(appContext);
        //通过createAsset接口创建图片文件
        let uri = await phAccessHelper.createAsset(photoAccessHelper.PhotoType.IMAGE, 'png'); // 创建媒体文件
        console.info('createAsset successfully, uri: ' + uri);
        let file = await fs.open(uri, fs.OpenMode.READ_WRITE || fs.OpenMode.CREATE);
        // 使用uri打开文件，可以持续写入内容，写入过程不受时间限制
        console.log(JSON.stringify(buffer))
        await fs.write(file.fd, buffer);
        // 关闭文件
        promptAction.showToast({
          message: "保存成功",
          duration: 2000
        });
        await fs.close(file);
      } catch (err) {
        console.error('createAsset failed, message = ', err);
      }
    })
  } catch (err) {
    console.info(`requestPermissionsFromUser call Failed! error: ${err.code}`);
  }
}

mediaLibrary已经提示被废弃，使用新版APIphotoAccessHelper需要新的权限。ohos.permission.WRITE\_IMAGEVIDEO和ohos.permission.READ\_IMAGEVIDEO为受限权限。

ohos.permission.WRITE\_IMAGEVIDEO权限参考：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/restricted-permissions-V5\#section1417080131712

ohos.permission.READ\_IMAGEVIDEO权限参考：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/restricted-permissions-V5\#section397164718158

使用受限权限，其申请方式请参考：
