Genesys Cloud Terraform: Queue skills not applying

Trying to define a queue with specific skills using the CX as Code vider. The queue creates fine, but the skills array stays empty in the UI. I’ve tried both the skills block and passing IDs directly. Here’s the snippet:

resource "genesyscloud_routing_queue" "test" {
 name = "Support"
 skills {
 id = "skill-id-123"
 }
}

Terraform apply succeeds with no errors. Checking the API directly shows no skills attached. Am I missing a dependency or is this a known issue with the vider?
