Create Extension (CRM) for Google Chrome -- 2

I need to create an extension to add some extra functions to WhatsApp Web (CRM)

- I need clean and organized source code
- Insert Kanban Mode
- Insert subscription system
- Multi languages
- Light and Dark Mode
- Being able to publish the Extension on the Google Web Store

I will provide an example extension to copy the same features.

I need you to create a new project directory.

Inside the directory, create the necessary files: manifest.json, popup.html, popup.js, content.js, styles.css, etc.

Declare the background scripts, content scripts, and popup HTML file.

Configure icons for the extension.

Design the popup UI using HTML to include buttons, settings, etc.

Implement language switcher, light/dark mode switching, and other UI elements.

Write JavaScript code to handle user interactions.

Implement functionality for Kanban mode, language switcher and light/dark mode toggle.

Implement Kanban mode and any other features that require direct interaction with the WhatsApp Web DOM.

Define the style of the extension's UI elements, ensuring responsiveness and
Implement light and dark styles.

Configure a server-side backend (using Node.js, Python, etc.) to handle user subscriptions.

Integrate a subscription system using a database to manage user accounts and payments.

Implement language files for each supported language.

Use JavaScript to dynamically switch between languages based on user preferences.

Test the extension thoroughly on different browsers.


That's all I need.
