Terraform : Invalid provider configuration for third-party providers

Question

I am facing issue to add third-party terraform provider, this is link I am following wiz. I added wiz provider in main.tf and root module as well. I am not sure what am I missing here. I have following code structure :

/root
/infra-module
    --> wiz-module
        - main.tf
            //required_providers{//aws //wiz}
        - providers.tf
        - data.tf
        - variables.tf
/terraform-deplyment
        - main.tf
        - providers.tf
            //required_providers{//wiz}
            //provider "wiz" {//clientid and secret}
        - data.tf
            //aws-secret-manager //secret
        - variables.tf
            //clientid
        - terraform.tfvars

Error facing is,

Providers are added in "terraform-deployment" as follows,

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~> 3.0"
      configuration_aliases = [ aws , aws.management]
    }
    wiz = {
      source  = "tf.app.wiz.io/wizsec/wiz"
    }    
  }
}
provider "wiz" {
    client_id = var.wiz_clientid
    secret = data.aws_secretsmanager_secret.get_wiz_secert.id
    alias = //tried adding alias
}

Thanks in advance
