provision azure ad b2c with resources in the tenant

I have the following terraform code :

terraform {
  required_version = ">= 1.1"

  required_providers {
    azurerm = {
      version = ">= 3.0.2"
    }
  }
  backend "azurerm" {}
  
}

provider "azurerm" {
  subscription_id = var.subscription_id
  features {}
}

provider "azurerm" {
    alias = "aad_b2c"
    tenant_id = azurerm_aadb2c_directory.example-b2c.tenant_id
    features {}
}

resource "azurerm_aadb2c_directory" "example-b2c" {
  country_code            = "FR"
  data_residency_location = "Europe"
  display_name            = "example"
  domain_name             = "example.onmicrosoft.com"
  resource_group_name     = azurerm_resource_group.main.name
  sku_name                = "PremiumP1"
}

resource "azuread_application" "demo" {
  provider = azurerm.aad_b2c
  display_name = "demo"
}

I got the following message :
The provider hashicorp/azurerm does not support resource type "azuread_application".

According to the documentation I cannot assigned a value which is an exported attribute to configure my provider. Is there any workarround to create an azure AD B2C tenant and some app registration inside ?

>Solution :

Based on the comments.

azuread_application is part of azuread provider, not the azurerm.
