Running on macOS here. This is a definitely a workaround, I'll give the game a go this way! However I do believe that having the ability to remap would be actually quite simple to implement.
Also while navigating works without changing the keyboard layout, I could not select the delivery because on an AZERTY keyboard you have to use Shift to use the numbers, and on macOS the default layout for AZERTY keyboards does not allow to use numbers when using Caps Lock but gives capitalised accented letters instead. Of course I can also change my keyboard layout, but that's not really convenient.
