如何使Touch Bar的内容可滚动？

Question

我正在尝试创建一个Visual Studio代码扩展，该扩展将向我的触摸栏添加有用的命令。我最多只能添加4个按钮，当它们消失时，它们就会消失。

我的package.json：

"contributes": {
    "commands": [
        {
            "command": "extension.commentLine",
            "title": "//"
        },
        {
            "command": "extension.commentBlock",
            "title": "/* */"
        },
        {
            "command": "extension.jumpTo",
            "title": "→ƒ"
        },
        {
            "command": "extension.rename",
            "title": "✎_"
        }
    ],
    "menus": {
        "touchBar": [
            {
                "command": "extension.commentLine",
                "group": "editing"
            },
            {
                "command": "extension.commentBlock",
                "group": "editing"
            },
            {
                "command": "extension.jumpTo",
                "group": "editing"
            },
            {
                "command": "extension.rename",
                "group": "editing"
            }
        ]
    }
}

如何添加更多按钮？也许使其可滚动？
