1.notificationManager.requestEnableNotification10+
支持设备Phone2in1TabletCarWearable
requestEnableNotification(context: UIAbilityContext, callback: AsyncCallback<void>): void
应用请求通知使能模态弹窗。使用callback异步回调。
仅当应用界面加载完成后（即调用loadContent成功），方可使用该接口。
模型约束：此接口仅可在Stage模型下使用。
系统能力：SystemCapability.Notification.Notification
 

示例

.import { BusinessError } from '@kit.BasicServicesKit';
.import { UIAbility } from '@kit.AbilityKit';
.import { window } from '@kit.ArkUI';
.import { hilog } from '@kit.PerformanceAnalysisKit';
.
.class MyAbility extends UIAbility {
.  onWindowStageCreate(windowStage: window.WindowStage) {
.  hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onWindowStageCreate');
.    windowStage.loadContent('pages/Index', (err, data) => {
.      if (err.code) {
.        hilog.error(0x0000, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err) ?? '');
.        return;

.      hilog.info(0x0000, 'testTag', 'Succeeded in loading the content. Data: %{public}s', JSON.stringify(data) ?? '');
