Simple, just open chrome extension as a page. To do that, follow below steps:

1. Open extension management page

3. Open extension as a page `chrome-extension:///popup.html`

- For example: [chrome-extension://npjcjlkchmiidojhockoecphakigbaej/popup.html](chrome-extension://npjcjlkchmiidojhockoecphakigbaej/popup.html)

chrome-extension://npjcjlkchmiidojhockoecphakigbaej/popup.html

## Privacy Policy file

Web stores require you to describe what the extension is or if you collect data of users. You also need to describe why you do that.

Make sure you include this file when you publish an extension, the web store may ask you to upload it.

**Note:** If you don't know how to write a privacy policy file, you can look at the [existing one](https://github.com/davidnguyen179/web-extension-boilerplate/blob/main/PRIVACY_POLICY.txt) attached on this repository.

## Badges

You can add badges to your project to indicate the version or to show how many users use your extension here:

## CI/CD with github action

You can modify the `.github/workflows` to show the CI/CD flow.
