Question about Apple Studio Display Standard

I bought this product a few days ago. Shipping took quite a long time and now I understand why: it doesn't have a Swiss plug, it comes from outside Switzerland. I have read several questions on this topic here at digitec. I bought the most expensive display variant just to have the Swiss plug. Doing nothing instead. The thorn is weird, never seen anything like it before. I don't even think it's a shuko. When I placed my order, a T12-C13 cable was automatically added to my cart. However, it was not included with the monitor. Can anyone tell me which adapter is the right one for this? Is this T12-C13 cable the right one? Looking at the photos and comparing them to the plug, it doesn't seem like it, but it could be.
