如何在Visual Studio代码中将新菜单项添加到“文件”菜单？

"activationEvents": [
  "onCommand:myExtension.showDate"
],
"menus": {
  "editor/title": [
    {
      "command": "myExtension.showDate",
      "group": "navigation",
      "when": "editorTextFocus",
      "title": "Show Current Date"
    }
  ]
},
"commands": [
  {
    "command": "myExtension.showDate",
    "title": "Show Date",
    "category": "My Extension"
  }
]

import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {
  let disposable = vscode.commands.registerCommand('myExtension.showDate', () => {
    let currentDate = new Date().toDateString();
    vscode.window.showInformationMessage(`Current Date: ${currentDate}`);
  });

  context.subscriptions.push(disposable);
}

export function deactivate() {}
