HarmonyOS鸿蒙Next中沉浸式代码导致PC全屏展示窗口按钮无法展示

HarmonyOS鸿蒙Next中沉浸式代码导致PC全屏展示窗口按钮无法展示 使用下面的代码实现沉浸式，但是在PC上会导致界面全屏展示，原有窗口的按钮都无法展示，这种该怎么处理？ 当前选择屏蔽PC，PC不做沉浸式，但是又有一个新问题，有些平板是跟PC类似的窗口模式，有些是类似手机的模式，这种该怎么处理？

// 1.实现沉浸式效果:获取应用主窗口
if (!KbdDeviceInfoUtil.getInstance().isPC()) {
  let windowClass: window.Window | null = null;
  windowStage.getMainWindow((err: BusinessError, data) => {
    let errCode: number = err.code;
    if (errCode) {
      Logger.error(TAG, `Failed to obtain the main window. Cause: ${err.message}`);
      return;
    }
    windowClass = data;
    Logger.info(TAG, 'Succeeded in obtaining the main window.');
    // 2.实现沉浸式效果：设置窗口为全屏布局，配合设置导航栏、状态栏的透明度、背景/文字颜色及高亮图标等属性，与主窗口显示保持协调一致。
    let isLayoutFullScreen = true;
    windowClass.setWindowLayoutFullScreen(isLayoutFullScreen, (err: BusinessError) => {
      let errCode: number = err.code;
      if (errCode) {
        Logger.error(TAG, `Failed to set the window layout to full-screen mode. Cause: ${err.message}`);
        return;
      }
      Logger.info(TAG, 'Succeeded in setting the window layout to full-screen mode.');
    });
    let sysBarProps: window.SystemBarProperties = { statusBarColor: '#F0F1F3', statusBarContentColor: '#000000', };
    windowClass.setWindowSystemBarProperties(sysBarProps, (err: BusinessError) => {
      let errCode: number = err.code;
      if (errCode) {
        Logger.error(TAG, `Failed to set the system bar properties. Cause: ${err.message}`);
        return;
      }
      Logger.info(TAG, 'Succeeded in setting the system bar properties.');
    });
  });
}
