为什么我的Chrome扩展程序无法突出显示多个关键字？

我需要帮助识别错误的谷歌浏览器扩展代码我试图使。
扩展应突出显示在活动的URL /标签上选择不同颜色的多个关键字。
由于我需要这个敏感数据，我不愿意使用类似的现有扩展，因为我完全业余的编码，我用ChatGPT代码的一些基本知识。
在最后的UI看起来不错，但问题是，扩展没有突出显示页面上的任何东西。
代码看起来不错，但我找不到扩展不工作的原因。任何帮助或洞察力是赞赏。
以下是所有文件：

我在这里找到了一些关于以前的清单版本2的解释，但这并没有帮助。聊天GPT无法检测到任何错误

如果chatGPT可以读取文档，它会知道“如果扩展操作指定了在单击当前选项卡时显示的弹出窗口，则不会调度action.onClicked事件。”

chrome.tabs.query({ active: true, currentWindow: true }, function (tabs) {
    chrome.scripting.executeScript({
      target: { tabId: tabs[0].id },
      files: ["content.js"],
    });
  });

int count = 1;在popup.js中
JS实际上是大小写敏感的语言，所以你需要在所有的js文件中将action改为“highlightKeywords”。例如，在content.js中，它是“highlightWords”，没有Key，大写W，当然这样的动作在代码中不存在。
