Exactly. There are several events in the Bible that make this clear, like the one you posted. Even Samson’s parents fell to the feet of an angel. They kept asking for its name until eventually the angel was like, why are you asking about my name? It’s beyond your understanding. Although personally, I feel this angel was Jesus. If Jesus would have told them His name, it was not time for that name to be told in that time in history. But that’s just my thoughts.
