How do I get the connection string out of the sql pool I have created in terraform.

Please see the code below, I cannot find anywhere how to output the any data from azurerm_synapse_sql_pool

resource "azurerm_storage_account" "telemetrystoragedl" {
  name                     = "${var.rg-name}telemstoredl"

  account_replication_type = "LRS"
  account_kind             = "StorageV2"
  is_hns_enabled           = "true"
}

output "altodatalake_name" {
  value = azurerm_storage_account.telemetrystoragedl.name
}

  value = azurerm_storage_account.telemetrystoragedl.primary_access_key
  sensitive = true
}
