In this testing environment I wired it to the 3.3 volt output of the Stamp. Not the best solution, ha ha, given the power the SIM7080 module needs. I am now converting it to powering the SIM7080 module with separate 5 volt line.
That should do the trick.
Hello @HappyUser
it is correct that M5StampC3 is supported by M5Unified library, but I can confirm that the library currently doesn't compile due to errors in Mic_Class.cpp and Power_Class.cpp.
I suspect that since there isn't much to gain from using a library like M5Unified for a stamp product (as @teastain already mentioned), M5Stack engineers aren't that alert in keeping the library updated.
Thanks

@felmue And indeed, I needed to add a delay before sending the payload. I had hoped that it would be necessary (in order to speed up he process of waking up, sending and going to sleep).

Thanks,
Indeed,
This works :
display.drawJpg(JPG_buffer_processed, Append_this_Struct.JPG_size, 0, 0, Append_this_Struct.JPG_width,Append_this_Struct.JPG_height,0,0,JPEG_DIV_2);
@felmue Thank you. Unfortunately currently I am using the other SIM7060 module. Well, I could power it down with an optocoupler or something like that. Maybe a good idea in future modules to incorporate the deep sleep logic.
