如何让uni-app开发的H5页面顶部原生标题和小程序的顶部标题不一致？

<script>
  export default {
    onLaunch() {
      // 监听各种跳转----------------------------------------
      ['navigateTo', 'redirectTo', 'reLaunch', 'switchTab', 'navigateBack', ].forEach(v => {
        uni.addInterceptor(v, {
          success: e => this.watchRouter(e),
        })
      });
      this.watchRouter();//首次路由跳转
    }, 
    methods: {
      watchRouter(d) {
        this.$nextTick(() => {
          document.title = `修改小程序顶部标题`;//修改小程序顶部标题
        });
      }, 
    },
  }
</script>
