HarmonyOS 系统权限申请弹窗点击禁止之后，立刻弹全局弹窗，全局弹窗没报错但没办法展示出来

可以通过增加setTimeout延时执行一下，参考示例：

requestPermission() {
  let atManager = abilityAccessCtrl.createAtManager();
  try {
    let context: Context = getContext(this) as common.UIAbilityContext;
    atManager.requestPermissionsFromUser(context, ["ohos.permission.CAMERA"]).then((data) => {
      let grantStatus: Array<number> = data.authResults;
      //延时执行弹窗
      setTimeout(() => {
        promptAction.openCustomDialog({
          builder: TestDialog.bind(this)
        }).then((dialogId: number) => {
          customDialogId = dialogId
        })
      }, 500)
    }).catch((err: BusinessError) => {
      console.info("data:" + JSON.stringify(err));
    })
  } catch (err) {
    console.log(`catch err->${JSON.stringify(err)}`);
  }
}
