我正在开发一个VS代码扩展，我想在状态栏中设置图标，但我面临的问题。

import * as vscode from 'vscode';
...
export function activate(context: vscode.ExtensionContext) {
    ...

    let disposable = vscode.commands.registerCommand('extension.helloWorld', () => { 
            ....
            //on the place of icon i want the icon to get display in the status bar
                  vscode.window.setStatusBarMessage(
                    "icon "+" icon "+  
                    data1 +
                    " icon " +
                    data2 +
                    " icon" +
                    data3
                  );
                  ...
                  ...
});
...
}

export function deactivate() {}
