The whole situation sucks. The US Tesla connector can only do single-phase AC charging, which makes it suboptimal for other countries and not fantastic for US commercial installations. The Tesla EU connector is a real standard and can do 3-phase charging. For reasons I haven’t fully deciphered (technical or regulatory?), EU Model 3 cars seem to use the CCS combo connector for supercharging, which is standardized but ugly and heavy. EU Model S cars use the regular (non-combo) adapter in a proprietary mode.

So there is an unnecessary difference between US and EU cars, even from the same manufacturer.
