from Hacker News

I'm trying to understand how requests and responses are sent inside a Whatsapp/Telegram web text chat.

My first idea has been inspect HTTPS requests/responses with "Network" tab from Firefox/Chrome Developers Tools, expecting to see some POST data but...for my surprise, when sending some text in Whatsapp/Telegram web to another person, there's no HTTPS request shown.None

What's going on? Thanks!
