Pixhawk 4 with the PM02 + F450 Frame

Hi, I am building a drone using the F450 DJI Frame, Pixhawk 4, and Power Module 02. I have been finding how to build it everywhere, but seem like nobody built it before because some ppl used Pixhawk 2, some used PM06 which there are some different features that confused me a lot despite the element I am using having similar functions. I am using Autopilot Mission Planner to program my drone, but I got stuck at “ESC Calibration”. When I powered it up with the battery, all motors reacted, but the ESCs seem like “don’t wanna work”. It might be a problem with my building(my ESC connection to the flight control is wrong, but I don’t know how to fix it - I am a newbie). This is kinda urgent, so if anyone is familiar with what I mentioned earlier, please help. I would appreciate it a lot. Thank you.
