Javascript 如何制作一个在chrome扩展中执行background.js的按钮？

我正在做一个chrome扩展。代码如下： Manifest.json：

{
"name": "My name!",
"version": "2.0",
"description": "Blocks ads",
"permissions": ["webRequest", "webRequestBlocking", "<all_urls>"],
"browser_action": {
    "default_icon": "shield.ico",
    "default_popup": "popup.html",
    "default_title": "Ad be gone"
},
"background": {
    "scripts": ["background.js"]
},
"manifest_version": 2
