Receiving properties with message from Azure IOT hub

[JB-Mars]

Hi, I can receive the message when sending a message from the Azure IOT hub to the ESP32 but cannot figure out how to retrieve the properties (key/value) that's part of the message, only thing returned is (const char* payLoad, int size) and payLoad only contains the message. Please see image below, thank you:
