如何使用react-native-navigatio v1制作顶层标签？ 这是我的bottomtabs代码，它很好用。 如何将此标签放在标题下方的顶部栏中

const startTabs = () => {
    Navigation.startTabBasedApp({
        tabs: [
            {
                screen: "my-app.FindPlaceScreen",
                label: "Find Place",
                title: "Find Place",
                icon: ..img,
                navigatorButtons: {
                    leftButtons: [
                        {
                            icon: sources[2],
                            title: "Menu",
                            id: "sideDrawerToggle"
                        } ] } },
            {
                screen: "my-app.SharePlaceScreen",
                label: "Share Place",
                title: "Share Place",
                icon: ..img,
                navigatorButtons: {
                    leftButtons: [
                        {
                            icon: sources[2],
                            title: "Menu",
                            id: "sideDrawerToggle"
                        } ]} }
        ],
        drawer: {
            left: {
                screen: "my-app.SideDrawer" 
            }
        }
