Simplest Pelion POC on Adafruit Feather

I’ve been working with an Adafruit Feather board and external modem wired in. With the latest mbed studio and mbed os cellular/os downloaded a week or so ago, the cellular example is working on this board. The question is: for a very simple POC, is it expected that the Pelion example (with no external spi storage and no porting for internal storage / i.e. stubbing things out) can in any way be successful even if some potential one-time operations have to occur again and again. I am working/reading through lots of docs now to get up to speed on this, but any suggestions would be greatly appreciated … all the way to the point of “there’s no way to this without some type of storage porting”.
