自定义导航栏的能力，好像只是将导航栏变透明，左上角的icon与右上角的反馈按钮、胶囊按钮依然无法隐藏。应该怎么操作才能隐藏？

{
  "navigationStyle": "custom", // 设置成custom
  "backgroundTextStyle": "dark",
  "navigationBarTitleText": "包裹中心",
  "disableScroll": true,
  "usingComponents": {
    "nav-bar": "../../components/navigationBar/navigationBar",
    "tabBar": "../../components/tabBar/tabBar"
  }
}
