如何配置Web组件的Dom Storage?

import web_webview from '@ohos.web.webview';
@Entry
@Component
struct Index {
  webviewController: web_webview.WebviewController = new web_webview.WebviewController();

  build() {
    Column() {
      Web({ src: 'www.example.com', controller: this.webviewController })
        .domStorageAccess(true)//
    }
    .width('100%')
    .height('100%')
    .justifyContent(FlexAlign.Center)
  }
}
