How come the Chrome extension listener is not getting activated on event?

As a beginner with Google Chrome extensions, I am struggling to output logs to the console from my background js. Furthermore, when there is an error such as a syntax issue, no error messages appear. In my manifest file, I have specified the name, version, manifest version, description, default icon, background.js script, and permissions, which are pageCapture and tabs. Within the background.js file, I have implemented an alert and a console.log statement. However, when the extension loads, the alert works as expected, while I do not see the console log statement being executed. Can you help me understand what I am doing wrong?

The issue is that the Developer Tools for the background page are not automatically launched by default. To open the Developer Tools, you will need to inspect the extension's background page while it is running. To do this, you can follow these steps: 1. Open your extension's options page by right-clicking on the extension icon and selecting "Options". 2. In the options page, click the link that says "Inspect views: background.html". 3. This will open the background page in a new DevTools window. From here, you should be able to see any console logs and debug your code as necessary. Alternatively, you could specify the persistent property in your manifest file's background section. This will cause Chrome to keep your background page running even when the extension popup is closed, allowing you to inspect the page using the regular DevTools. Here's an example of what your background section would look like: 
"background": {
  "persistent": true,
  "scripts": ["background.js"]
},
;
