Type of issue
Missing information

Feedback
When using az lab vm commands, it's possible to use in some cases the --artifacts argument. However, the schema expected for this argument is specified nowhere. I tried extracting it from the ARM template of the formula in the portal, it does not work. There are no links to documentation regarding this file.
