V3 supports Tesla's implementation of "NACS", which is not what was opened up to everyone. You're more than welcome to grab a NACS-CCS conversion plug to try, it won't work because it's not speaking NACS protocol, it only has the NACS connector.
Right now there's only a handful of "magic dock" truly CCS/NACS compatible superchargers that speaks the CCS/NACS protocol that works with non-Tesla vehicles[1].
