Terraform: Genesys Cloud queue skills not applying

General Discussion
1

I’m trying to define a queue with specific skills using the CX as Code provider, but the skills aren’t sticking. Here is the block:

resource "genesyscloud_routing_queue" "test_queue" {
 name = "Test Queue"
 skills {
 id = "123-456-789"
 }
}

The apply succeeds, but the queue shows no skills in the UI. Am I missing a nested block or is this a known issue?
