Azure CLI did it this way:
https://github.com/Azure/azure-xplat-cli/blob/f261c839e96479c1520287db806926ff66b29a83/lib/util/profile/environment.js

this includes German and USGoverment Cloud and others, probably having a similar configuration and the same names will be useful to make changes going forward
