The only one I've encountered for now is Google Messages. What about Messenger and WhatsApp? I've read they support the native chat bubbles but I can't seem to find the option for it. The only option in Messenger are their custom chat heads but I don't see an option for Android's native chat bubbles. Even Facebook's support page mentions that Messenger supports native chat bubbles but I don't see the option in the place they say it should be. For reference, I'm running Samsung's One UI 6/Android 14.
