How to build drone using DJI Snail propulsion system

Hi, I was reading some of the DJI components.

I was thinking of assemble some drone system myself.
Reading through SNAIL spec, I did not see much about pin connections.
I roughly know one side is 3 pins to the motor, and the other side is GND/VDD, with two additional wires.
Flight controller supposed to drive the two additional wires.
Are there any electronic spec of how the two wires are to be driven.
If there is anybody who had DIY using these types of components, please do help me!
I might have some more questions regarding the flight controller.
Thank you very much!

You are correct, the 2 additional wires are receiving a PWM (Pulse Width Modulation) signal from the flight controller. Then the ESC sends a three phased PWM square wave to the motors.
