When does the demo of the switch game, The Legend of Zelda: Echoes of Wisdom

As of my last knowledge update in October 2023, there hasn't been any official announcement regarding a game titled "The Legend of Zelda: Echoes of Wisdom." It's possible that new games or demos have been announced after that date. For the most accurate and up-to-date information, I recommend checking official Nintendo sources, gaming news websites, or the Nintendo eShop.
