如何在我的vscode扩展中的自定义viewsContainers图标上显示徽章计数？

"viewsContainers": {
  "myContainer": {
    "title": "My Container",
    "icon": "myContainer.svg"
  }
}

"views": {
  "myView": {
    "name": "My View",
    "container": "myContainer"
  }
}

const treeDataProvider = new MyTreeDataProvider();
const treeView = vscode.window.createTreeView('myView', { treeDataProvider });

class MyTreeDataProvider {
  getTreeItem(element) {
    const treeItem = new vscode.TreeItem(element.label);
    treeItem.collapsibleState = vscode.TreeItemCollapsibleState.None;
    treeItem.description = element.description;
    treeItem.tooltip = element.tooltip;
    treeItem.iconPath = element.iconPath;
    treeItem.contextValue = element.contextValue;
    treeItem.resourceUri = element.resourceUri;
    treeItem.command = element.command;
    treeItem.badge = element.badge; // 设置徽章计数
    return treeItem;
  }

  getChildren(element) {
    // 返回树节点的子节点
  }
}

const myTreeItem = {
  label: 'My Tree Item',
  description: 'Item description',
  tooltip: 'Item tooltip',
  iconPath: new vscode.ThemeIcon('file'),
  contextValue: 'myTreeItem',
  resourceUri: vscode.Uri.file('/path/to/file'),
  command: {
    command: 'extension.myCommand',
    title: 'My Command'
  },
  badge: '10' // 设置徽章计数
};

treeView.reveal(myTreeItem);
