I have been trying to connect to the IoT cloud using my Arduino Uno and an ESP01.

The IoT cloud does not recognize my device as genuine. Hence, I've been trying to create a thing and connecting it as a third-party device. I have an ESP01 WiFi module that I want to use to connect to the IoT cloud.

I tried the following connection:

Arduino ----> ESP-01  
3.3V  ------> 3v3  
3.3V  ------> EN(CH_PD)  
TX(1) ------> TX  
RX(0) ------> RX  
GND   ------> GND

I also tried to reverse the connections of the RX and TX pins. Still no success. I want to connect to the cloud and use some sensors to update the cloud variables. How do I do it? Any kind of help is highly appreciated.

Edit: I tried to upload the code that thd cloud editor provided and it throws and error saying:

fatal error: list: No such file or directory
 #include <list>
