如何唤起应用的系统权限管理页和查看对应权限状态？

import common from '@ohos.app.ability.common'; 
@Entry 
@Component 
struct Index6 { 
  build() { 
    Row() { 
      Column() { 
        Button("访问应用信息").onClick(()=> { 
          let context = getContext(this) as common.UIAbilityContext; 
          context.startAbility({ 
            bundleName: 'com.example.xxx.settings', 
            abilityName: 'com.example.xxx.settings.MainAbility', 
            uri: 'application_info_entry', 
            parameters: { 
              pushParams: 'com.example.mynavigation'//传要跳转的对应应用的包名 
            } 
          }); 
        }).margin(10) 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
}
