In John 12, which group came to Philip saying, "Sir, we want to see Jesus"?

Answer: Some Greeks

Greeks who came to worship at the feast asked Philip of Bethsaida; he told Andrew, and both went to tell Jesus.

“Now there were some Greeks among those who went up to worship at the feast. They came to Philip, who was from Bethsaida in Galilee, and requested of him, “Sir, we want to see Jesus.” Philip relayed this appeal to Andrew, and both of them went and told Jesus.”— John 12:20-22 (BSB)
