implementing amazon cognito for authentication

[pksher]

Hi guys. I have made an application using esp32 devkit C v4 that sends data to aws iot console, using the example in the esp-idf. It is working, however, the client wants to have user sign in stuff using amazon cognito. So i want to know what should be added to the esp32 side for this purpose.

Your suggestions will be appreciated

Thanks and Regards,
