HarmonyOS app的桌面显示的名称应该怎么获取？

import common from '@ohos.app.ability.common'; 
import { bundleManager } from '@kit.AbilityKit'; 
 
@Entry 
@Component 
struct Index { 
  @State appName: string = ''; 
  @State windowAppName: string = ''; 
 
  aboutToAppear(): void { 
    const context = getContext(this) as common.UIAbilityContext 
    // 获取系统app的名称 
    let bundleFlags = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_APPLICATION 
    let bundleInfo = bundleManager.getBundleInfoForSelfSync(bundleFlags); 
    this.appName = context.resourceManager.getStringSync(bundleInfo.appInfo.labelId) 
 
    // 获取桌面app的名称 
    this.windowAppName = context.resourceManager.getStringSync(context.abilityInfo.labelId) 
  } 
 
  build() { 
    Row() { 
      Column() { 
        Text('系统的app名称: ' + this.appName) 
          .fontSize(20) 
 
        Text('桌面的app名称: ' + this.windowAppName) 
          .fontSize(20) 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
}
