(Unicode C) Azure REST API Access TokenDemonstrates how to request an Azure REST API OAUTH2 access token. Note: In order to access resources a Service Principal needs to be created in your Tenant. It is really convenient to do it via AZ CLI: az ad sp create-for-rbac --name [APP_NAME] --password [CLIENT_SECRET]
