Appointment Availability Checker Extension

I'm looking for a personal project to develop a browser extension that can check the availability of appointments on a specific site, send me notifications via Telegram, refresh the appointment table without needing to completely refresh the page, and automatically book appointments.

The site in question is: https://i2-auth.visas-fr.tlscontact.com/.

Ideal Skills:
- Proficient in developing browser extensions
- Familiarity with the specified site
- Experience with creating Telegram bots or integrating with Telegram API
- Knowledge of web scraping
- Understanding of automating web tasks

I'm looking for someone who can make this project efficient and reliable. Please provide examples of similar work you've done in the past.
