this is good, but in whatsapp bussiness @bot is still a normal jid or sometimes a @c.us user

Has anyone tried it? is it work?

👍 👍 👍

1. Remove the jid map
2. add Usync protocol support (to get bot info)
3. add a store for message secrets (hard until Storage format is released)
4. type formatting, linting
5. Eliminate the need for @s.whatsapp.net entirely (whatsapp bots do not need that)

We should spearhead msmsg support as soon as possible. If @vphelipe isn't willing to apply the changes I mentioned, I'll look into implementing it myself instead.

Aldo we need a better store based in mysql so we can handle the bot messages, polls etc
