How It Works:

1. Google Authentication: The extension authenticates your Google account and monitors a custom label (e.g., "OTP") in Gmail for relevant emails.

2. Real-Time Email Monitoring: Google Pub/Sub tracks changes in the labeled emails and sends a push notification to a webhook(backend server) when a new email arrives and push the email data(historyid) to websocket.

3. Instant Notifications via WebSockets: Chrome extension establish connection with websocket and recieves email history id instantly.

4. Email Retrieval & AI Processing: The extension pulls the new email content, then sends it to an AI model (Gemini/OpenAI) to extract OTPs or verification links.

5. Popup & Autofill: The extracted OTP or link is displayed in a popup. OTPs are automatically filled, and verification links can be opened in a new tab.

6. Client-Side Privacy: Google auth tokens are handled entirely in the browser, ensuring they are not shared with the backend.
