有没有办法通过VS代码扩展API来选择/设置主题？

import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {
    let disposable = vscode.commands.registerCommand('extension.setTheme', () => {
        const themes = ['Default Light', 'Default Dark', 'Monokai'];
        vscode.window.showQuickPick(themes).then((theme) => {
            if (theme) {
                const config = vscode.workspace.getConfiguration();
                config.update("workbench.colorTheme", theme, true);
            }
        });
    });

    context.subscriptions.push(disposable);
}
