Google chrome extension 我如何让我的chrome扩展启动并运行？

编辑：代码中似乎有问题。有人知道如何修复这个错误吗

我得到的错误是： 未捕获的语法错误：意外标记“'）”

contentscript.js:103（匿名函数）

就上下文而言，我不是一个开发人员或软件工程师，只是一个对IBM Watson的产品感兴趣的普通人。我想构建我自己的Chrome扩展，它可以分析我从笔记本电脑上写下的信息的音调，所以我遵循了IBM手册中描述的所有步骤。令我惊讶的是，尽管我的技术知识有限，我还是设法完成了本文档中描述的步骤

在执行步骤5之后，我看到我的扩展成功地显示在中chrome://extensions/

但是，我无法重现步骤6。右键单击时，不会显示IBM watson API菜单

我错过了什么？有人有任何指示吗？

切换到具有普通网页的选项卡，然后在那里尝试。如果选项卡不起作用，请重新加载它。我已经尝试过了，但再次分析后，问题似乎出现在代码中-更多详细信息见下面的注释
