How to implement Device agent on nrf device

[YvanTankeu]

I want to do the FOTA mass update and the solution I'm interested in is via the Azure Device Update, so I followed this tutorial https://shorturl.at/tvxRZ which I'm trying to adapt to my nrf7002dk IoT device since it's not an ESP32 and it's not freeRTOS but rather a nrf700dk with ZephyrRTOS on the NCS. For the question about the device update agent, no I haven't done it because I don't know much about it, how do you think I can implement it for my nrf device because the example I'm following doesn't lead anywhere.
