Want to authenticate in synapse spark pool using managed identity.

I'm looking for a way to authenticate within the synapse spark pool, using the MSI.

Managed Identity Support is already available in a variety of other Azure platforms via the nuget called Azure.Identity. Here is a list of products that support "**DefaultAzureCredential**":
https://www.nuget.org/packages/Azure.Identity#readme-body-tab

- Azure Virtual Machines
- Azure App Service and Azure Functions
- Azure Kubernetes Service
- etc

Whenever this is supported, it becomes possible to create an MSAL access token for a list of scopes WITHOUT providing an additional service principal or secret. Here is an example of authentication to Azure Analysis Services:

**using Azure.Core;
using Azure.Identity;
using Microsoft.Identity.Client;**

> private static Azure.Core.AccessToken GetAzureAccessTokenFromDefaultCredential()
> {
> TokenCredential p_CurrentTokenCredential = null;
> string[] p_ScopesList = null;
>
>
> // Retrieve the current credentials (for the app service)
> p_CurrentTokenCredential = new DefaultAzureCredential(includeInteractiveCredentials: true);
>
>
> // Special-purpose scope used for
> // application permissions
> p_ScopesList = new string[] { "https://*.asazure.windows.net/.default" };
>
>
>
> // The context and the resulting token.
> var ContextObj = new TokenRequestContext(p_ScopesList);
> Azure.Core.AccessToken TokenObj = p_CurrentTokenCredential.GetToken(ContextObj, CancellationToken.None);
> return TokenObj;
> }

Is there any way to accomplish the same thing in synapse spark pools today? I had found the "TokenLibrary" but it seemed extremely limited and I found no way of creating an access token for an arbitrary list of scopes.

Any tips or pointers would be very much appreciated.
