Apple doesn't make one.
Do you want to have to schlepp around a whole other seperate full keyboard around with that iPad Pro?
I can give you a link to a great wireless, Bluetooth Apple style full keyboard with keypad with backlighting , but this will be more bulk to lug around, unless you want to purchase and use a different type of case for your iPad Pro and a seperate, detached wireless keyboard, instead.
I gave you the wireless calculator keypads as a much smaller, compact hardware option.
There is this Bluetooth keyboard from Logitech.

I do not use any Apple keyboard cover with my iPad Pro.
I prefer to use a a premium iPad folio style case ( no built-in keyboard ) and use a seperate Bluetooth keyboard, as I can put my iPad anywhere close to me and just have the keyboard in my lap.
Here is the one I purchased long ago and use.
