Hi folks! Maybe I am being silly, so happy to be corrected, but I can’t seem to access the Balena Fleet ID (or as its called in the documentation “APP\_ID”) from within a container. Would it be possible to add this as a standard fleet environment variable just as the device unique ID is a standard environment variable for variable for all devices?  
Thanks in advance!

Hi, ordinarily we try prefer using the fleet slug for unique identification, rather than the fleet id. Would you mind sharing what you are trying to do from within the container and why the slug is insufficient?
