Controlling Brushless motors with an ESC

[TSwin.1]

I'm working on using an STM32F446RE board to control two brushless motors using a SimonK ESC (https://www.amazon.com/dp/B07NMJRJKJ?psc=1&ref=ppx_yo2_dt_b_product_details) (sorry I don't know how to shorten the link) now normally these types of products are on drone etc and are written to with some sort of radio receiver. I was wondering how I go about writing to this ESC to control a brushless motor with STM32F446RE
