ApplicationRegion parameter does not work with output from ARM

Describe the bug I have a compute resource in Azure, lets say an AKS cluster. Doesn’t really matter which one since the problem is the same across multiple services:

In my deployment pipeline I run a CLI command to retrieve the region, for instance: az aks show --resource-group my-rg -n mycluster --query "location" --output tsv

This outputs something like northeurope or eastus2. This seems consistent across many Azure resources.

Now, I want to use that output to feed into an app setting which I then want to use to configure my Cosmos DB client with ApplicationRegion:

CosmosClientBuilder clientBuilder = new CosmosClientBuilder(SysConfig.CosmosEndpointUri, SysConfig.CosmosPrimaryKey);
var builderOptions = clientBuilder.WithApplicationRegion(Environment.GetEnvironmentVariable("AZURE_REGION"));

Turns out, you can’t. Because the SDK wants North Europe or East US 2. I don’t see any way how to programmatically split this up

To Reproduce See above.

Expected behavior The SDK should accept standard naming input for Azure regions like northeurope.

Actual behavior See above.

Environment summary SDK Version: 3.14.0

Should we expect this to be fixed? It is going to be two-year anniversary of this request soon. Does it really take that long to hard code a table or use equality comparer on the existing one that will do .ToLowerInvariant().Replace(" ", "")?

@ealsur your example is a "regionType": "Logical", I think you can disregard those. Looking at the output I would say only "regionType": "Physical" is important as those are actual regions.

Physical ones seeem to follow the logic, lowercase, no spaces, not special chars
