Is there a way to apply policy tags to columns in BigQuery via Terraform? - google-cloud-platform

Question

Is there a way to apply policy tags to columns in BigQuery (GCP) via Terraform? Any pointers would be appreciated. I believe we can create policy tags and taxonomies like this.
But how do I map/apply them to a column in a table? E.g such as the one given below, I’m creating a table using terraform and want to apply a policy tag to one of its columns. Any tutorials, code samples, guides etc. would be highly appreciated if there exists a possibility to do this via Terraform:
resource "google_bigquery_table" "table_with_pii" {
provider = google-beta
dataset_id = google_bigquery_dataset.integration_testing_dataset.dataset_id
table_id = "table_with_pii"
schema = <<EOF
[
{
"name": "col1",
"type": "STRING",
"mode": "NULLABLE",
"description": "This is col1. It's a PII column."
},
{
"name": "col2",
"type": "BOOLEAN",
"mode": "NULLABLE",
"description": "This is col2"
}
]
EOF
}
I've scanned through the relevant resources on the Terraform registry but I haven't come across such options yet. I'm not sure if the code block mentioned in this thread is a rolled out feature of just pseudo-code. Because, whenever, I run terraform validate after adding such a mapping, I get the error that policy_tags is not a valid option. Am I missing something?
