HarmonyOS 鸿蒙Next中浏览器申请麦克风、摄像头权限会导致多次申请

HarmonyOS 鸿蒙Next中浏览器申请麦克风、摄像头权限会导致多次申请 能否web只申请一次权限请求，而不是每次进web都要去申请，我这边找到了个官网的例子，没太理解，这代码即是应用侧申请了，web侧又申请了？

import { webview } from '@kit.ArkWeb';
import { abilityAccessCtrl } from '@kit.AbilityKit';

@Component
struct WebComponent {
  controller: webview.WebviewController = new webview.WebviewController()

  aboutToAppear() {
    // 配置Web开启调试模式
    webview.WebviewController.setWebDebuggingAccess(true);
    let atManager = abilityAccessCtrl.createAtManager();
    atManager.requestPermissionsFromUser(getContext(this), ['ohos.permission.CAMERA', 'ohos.permission.MICROPHONE'])
      .then(data => {
        let result: Array<number> = data.authResults;
        let hasPermissions1 = true;
        result.forEach(item => {
          if (item === -1) {
            hasPermissions1 = false;
          }
        })
        if (hasPermissions1) {
          console.info("hasPermissions1");
        } else {
          console.info(" not hasPermissions1");
        }
      }).catch(() => {
      return;
    });
  }

  build() {
    Column() {
      Web({ src: $rawfile('index.html'), controller: this.controller })
        .onPermissionRequest(event => {
          if (event) {
            AlertDialog.show({
              title: 'title',
              message: 'text',
              primaryButton: {
                value: 'deny',
                action: () => {
                  event.request.deny();
                }
              },
              secondaryButton: {
                value: 'onConfirm',
                action: () => {
                  event.request.grant(event.request.getAccessibleResource());
                }
              },
              cancel: () => {
                event.request.deny();
              }
            })
          }
        })
    }
  }
}
