KinCony ESP32 Tuya IoT adapter and Tuya app

[Dana]

Good evening, 
I am using Kincony kc868-atc v1 board, to connect my modbus device, I want to interface it with tuya application.
I want to build my own interface, but all the tutorials uses a ready interface. the other tutorials suggest burning the authorization to an ESP module so it can interface with tuya platform, but in our case we have the CBU-IPEX module, how can I build an interface on tuya, does it require licensing?

Also, does the  kincony esp32 bin file firmware interfere with the arduino file? 

thank you
