Has checkmate ever been achieved by castling kingside in a high-level game?

I asked an AI large language model, but it listed games which certainly didn't achieve checkmate with castling kingside. I also tried searching the web but didn't come across any.

    ChatGPT is great at acting like it knows the answer, not so much at actually answering. Morphy did it once in an odds game: chessgames.com/perl/chessgame?gid=1238144

    ChatGPT is great at acting like it knows the answer, even when answering pure bullshit. Anderssen didn't castle at all in the Immortal Game - and neither did Kieseritzky. Morphy castled queenside against Brunswick & Isouard.

    This sounds like something a simple cql query could solve, right? I don't have a proper database to run it on...

    I am only aware of a (blitz) game (White was Eduard Lasker , a brother of world champion Emanuel Lasker) where White mated by castling queenside , but not with the king side as desired.

According to that CQL query :

cql(input Megabase2023.pgn)

move previous from [Kk] o-o

There are twelve games where the castling king side delivered a checkmate, 4 of which played by 1600+ players
