I am try to create a mini wifi repeater using ESP32 but I kept getting error trying to build it

I am new here, or should I say I have no idea about this HCI(Human Computer Interaction).

I am new But I wanna just create a mini router repeater/extender that:

-Lets a device connect to ESP32 hotspot
-Allow ESP32 to be a middleman between device and wifi

I know a little about programming(im an it student) but I didn't dig too deep in it. I have made ChatGPT write me a code for the ESP32 to do this.
The problem is;
-Arduino IDE doesn't support NAT(Network Address Translation). -ChatGPT
-ESP-IDF always sends me errors that confuses ChatGPT.
-I don't understand it so I can't debug it myself.
I will paste the codes that ChatGPT wrote below:

There are a lot of error after running

that is where I am having trouble.

Hope anyone can help me with this.
I also hope that no one would be disappointed if I don't understand instructions.
