Terraform Azure Tag for user who executed code

I have to add a tag in Azure Resource while deploying it through Terraform, this tag should automatically fetch username/email who executing the code. Is there anyway we can refer this in Terraform code like some function?
I want to add CreatedBy tag which should automatically put username in Azure-

    tags                =   {
                          Business = var.business
                          Organization = var.company
                          Environment = var.env
                          CreatedOn =  formatdate("YYYY-MM-DD hh:mm ZZZ", timestamp())
                          **CreatedBy = <>**
