When working with Azure Databricks (with VNET injection) to connect securely to an Azure Storage account via private endpoint, there's a few locations it needs to connect to, firstly the vnet that databricks is connected to, which works well when connecting with blob client in a notebook.
Then connecting to serverless compute following this guide: Configure private connectivity from serverless compute - Azure Databricks | Microsoft Learn, which doesn't seem to work, as then performing the same operation errors with `This request is not authorized to perform this operation.`

But most importantly, none of this touches on the control plane, which Unity Catalog uses for external locations, and I can't seem to find documentation on how to create a private endpoint to the control plane at all?

Is there any guidance on how to create an external location using private endpoint Azure Storage account? Trying to create it ends with error: `Failed to access cloud storage: [AbfsRestOperationException] () exceptionTraceId=XXX`, and now other details.
