如何跳转到商店应用下载的位置？

import Want from '@ohos.app.ability.Want';  
import common from '@ohos.app.ability.common';  
  
@Entry  
@Component  
struct Index {  
  @State appId: string = 要跳转的AppID；  
  controller: TextInputController = new TextInputController();  
  build() {  
    Row() {  
      Column() {  
        TextInput({ text: this.appId, placeholder: '请输入应用的appId', controller: this.controller })  
          .width('90%')  
          .onChange((value: string) => {  
            this.appId = value  
          })  
        Button('点击跳转到HarmonyOS版应用市场详情页面')  
          .margin({top: 50})  
          .onClick(()=>{  
            const want: Want = {  
              uri: `store://appgallery.huawei.com/app/detail?id=${this.appId}`  
            };  
            const context = getContext(this) as common.UIAbilityContext;  
            context.startAbility(want).then(()=>{  
              //拉起成功  
            }).catch(()=>{  
              // 拉起失败  
            });  
          })  
      }  
      .width('100%')  
    }  
    .height('100%')  
  }  
}
