I think OP is not looking for an encrypted chat but rather looking for a replacement app to send unencrypted SMS messages (and store them encrypted on the device) like Signal has done since it was called TextSecure and is finally going to stop doing now.
Matrix / element or XMPP. I’ve been using it for years now both for friends / fam, and for group chats.
