Not every control binding will effect the Fenix A32X, due to it's externalised architecture. Please see below for the default key bindings which we've added to the Fenix A32X.
Of course, you can change these keyboard bindings within MSFS, as is your prerogative. We've listed what the default keybinds are to help you just a smidge.
Alternatively, the native document available to you is here.
