According to page below, I should select my specific esp8266 board:
https://www.kincony.com/build-esp8266-web-serve.html

According to page below the product KC868-A32 uses Espressif ESP32:
https://tr.aliexpress.com/item/1005004042030033.html

But I couldnot find it on below menu:
Arduino IDE 2.0.4 > Tools > Board > esp8266 > ...

Could you help me on selecting the correct board.

if you use KC868-A32, it made by "ESP32" , chose "NodeMcu-32S" board.

According to tutorial below
https://www.kincony.com/build-esp8266-web-serve.html
with ref: http://arduino.esp8266.com/stable/packag...index.json
I could not see "NodeMcu-32S"

Then I found your tutorial
Lesson1-config Arduino IDE for ESP32 module (kincony.com)
with ref:  https://dl.espressif.com/dl/package_esp32_index.json
There is a "NodeMcu-32S" option. And as you said it is made by esp32

Thanks

I made a clean-up by following here
Then I extracted arudino from the zip file from here
Then I add esp32 boards by following here (link updated)
Then I selected NodeMCU-32S under the menu esp32 as below (is it answer to your question?).
   

But there is a compile error:

I tried every board under the menu esp32 that has "esp32" in its name. But the error persists.

Board Manager: Yes I checked it. esp32 is version 1.0.6.
Library Manager: I think header files are related with library manager. Now, for no reason, it started giving me below error
Code:
Compilation error: PCF8574.h: No such file or directory
I need to find which libraries should i install to use the above example.

I have put the PCF8574 library, under library folder, under sketchbook location. 
For my case it is C:\me\codes\arduino\libraries
And it worked. 
   

But, now the below compile error came back.
Code:
Compilation error: WiFiManager.h: No such file or directory
