In-game voice chat should work already. At least it did a few weeks ago, as I had a VoG run with 2 players each on Steam, XBox, and Playstation. The quality of in-game chat is still not as good as discord or an XBox party (never played on playstation, so I have no basis for comparison there), but it worked fine then. Unfortunately, still no text chat for console, but that was supposed to come later this year.
