HarmonyOS 应用系统设置中权限操作结果如何感知

static openPermissionsInSystemSettings(): void { 
  let wantInfo: Want = { 
    bundleName: 'xxxx', 
    abilityName: 'xxxx', 
    uri: 'application_info_entry', 
    parameters: { 
      pushParams: 'xxx.xxx.xxx' // 应用的 bundleName 
    } 
  } 
  let context = getContext() as common.UIAbilityContext; 
  context.startAbility(wantInfo).then(() => { 
  // ... 
}).catch((err: BusinessError) => { 
  // ... 
})
