HarmonyOS 如何调用默认浏览器观看视频

请参考以下demo：

import common from '@ohos.app.ability.common';
import { Want } from '@kit.AbilityKit';

@Entry
@Component
struct Browsers {
  @State message: string = 'Hello World'
  private context = getContext(this) as common.UIAbilityContext
  startMMSAbilityExplicit() {
    // 这里完善联系人和号码
    let want: Want = {
      action: 'ohos.want.action.viewData',
      entities: ['entity.system.browsable'],
      // 想要跳转的地址
      uri: 'https://www.huawei.com/'
    }
    this.context.startAbilityForResult(want).then((data) => {
      console.log("Success" + JSON.stringify(data))
    }).catch(() => {
      console.log("error")
    })
  }
  build() {baidu
    Row() {
      Column() {
        Button('跳转浏览器')
          .onClick(() => {
            this.startMMSAbilityExplicit();
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
