I did not need any driver, macOS has a pretty descent support for keyboard.

Did you try switching your keyboard preference from Apple to PC Layout in keyboard preferences?

I did not try on M1, but this keyboard works pretty well with a MacBookPro early 2015 (and it was for a French Azerty Sculpt keyboard, not even the regular US Qwerty!).

Pro tip: on a Mac laptop, add a key shortcut to switch between the 2 layouts, so that you can quickly switch from one to the other layout.

Also add the keyboard icon / input source in the menu bar, for quick visual check : it shows the actual keyboard layout.
