Service Principal Creation by Terraform doesn't provide password/secret in the output

when generating Service Principal in Azure manually, as a result of the operation I'm provided a password.

It's not the case however if I create service principal with Terraform, the password is not among the outputs of this module:

  + azuread_service_principal.k8s_principal
      id:                <computed>
      application_id:    "${azuread_application.app.application_id}"
      display_name:      <computed>

Is there anything I missed? Why does the Terraform behavior differs in the output compared to CLI?

to who using newer version of Terraform, you don't need to preset the password, following code is working fine:

    resource "azuread_service_principal_password" "auth_pwd" {
      service_principal_id = azuread_service_principal.auth.id
    }
    
    output "auth_client_secret" {
      value = azuread_service_principal_password.auth_pwd.value
      description = "output password"
      sensitive = true
    }

then you can run the following cli to retrieve the password:

terraform output -raw auth_client_secret

tested on terraform 1.0.10, hashicorp/azuread provider 2.11
