I use Terraform by deploying an Azure OpenAI resource by the following code:

resource "azurerm_cognitive_account" "openai" {
  name                = var.openai_name
  location            = var.resource_location
  resource_group_name = var.resource_group_name

  kind     = "OpenAI"
  sku_name = "S0"
}

However, this code seems to deploy an Azure OpenAI resource with a region based endpoint instead of a resource based endpoint. See here the difference when I do it via the Azure portal vs via Terraform code:

From the portal

vs.

Using Terraform code

Why does this happen and how can I create an Azure OpenAI resource with a region based endpoint using Terraform?
