Stepper motor driver in flowcode?

I'm new to Flowcode, so I'm hoping someone can help me with this. I'm trying to control a Nema 23 stepper motor ( https://www.oyostepper.de/category-7-b0-Nema-23-Schrittmotor.html ) using a motor driver and an Arduino Nano. I'm not sure how to program this in Flowcode. In Flowcode, the stepper motor output assumes you're connecting the stepper motor coils directly to the microcontroller, but there doesn't seem to be a way to select a motor driver output using the STP DIR and ENA pins. There have been a number of posts on this forum, seemingly from other beginners in a similar situation to me, mentioning using LED outputs and other methods to presumably replicate the driver, but I can't find any clear instructions explaining how to do this in FC7, and they're quite difficult for a beginner to follow. Can someone please help me with this?
