Terraform Import State for Genesys Cloud User Resources

Could someone explain the correct syntax for importing existing Genesys Cloud user resources into Terraform state using the provider?

I am attempting to run terraform import for a genesyscloud_user resource. The documentation is sparse on the exact identifier format required.

I have tried using the numeric user ID directly. The command fails with a 404 Not Found error from the API layer.

Is the import identifier expected to be the UUID string instead? I need to map our legacy users to IaC without recreation.
