Implement the invite link logic for group participants

This needs to be implemented on the Docker simulator. Whenever someone clicks on the invite participant link, the Docker should store its whatsapp_id and phone number in the database and also include its whatsapp id in the relevant group participant list

Work on this was done yesterday. I will mark it resolved after testing it with dayem's Webhook code.
