Can you make on the Brax3 a virtual space for whatsapp etc. For more private communication.
Settings > Security & privacy > Private space
Is that enough for anonymous chat?
What do you mean anonymous chat ? Whatsapp specifically knows your Phone number, your contacts, your IP etc
The only private chat is the Session messenger, it doesn’t need a phone number and everything is encrypted, your ID is a public key generated by a private key.
