RC from SIYI MK32 to PX4 Autopilot

What do I need to recieve remote control from a ground station (SIYI MK32) in PX4 Autopilot installed on linux? Do I need it’s air unit? Or can I use QGC on gs for recieving manual input from gs’s sticks and magicaly pass it to PX4 Autopilot? I’m completely new to this and just can’t figure out how to link these components together
