I suggest to have a magic link sent through WhatsApp for authentication.

There are two approaches.
**__Approach 1:__**
1) User chooses WhatsApp a method to sign-in
2) redirected to whatssap, with a message "sign-in" ready to be sent to bot
3) once sent by the user
4) the bot replys back with a magic link to sign-in

**__Approach 2:__**
1) User chooses WhatsApp a method to sign-in
2) User enters his whatsapp number
3) User recieves a magic link to sign-in

can u expand on this a bit? as far as i can tell supabase magic links are only available for email auth. how would i integrate the magic link sent via whatsapp with supabase auth?
