Entering Hanja (Korean) on Surface Laptop (Copilot+ PC) (US version)

Hello,

I bought the US version of the new Surface Laptop (Copilot+ PC) (13 ") last week. I regularly type in Korean and have just noticed that the new Copilot button has replaced the button next to the Right Alt key which is used to input Hanja on the Windows Korean keyboard. How do I do this now?

Thank you so much!

Best regards from New Orleans.
