Genesyscloud_user schema change in v1.35.0 breaking existing HCL

Upgraded the Terraform provider to v1.35.0 and our existing genesyscloud_user resources are failing validation. The error says email is no longer a required attribute, but removing it causes a plan diff error claiming it’s missing. Here’s the config:

resource "genesyscloud_user" "agent" {
 email = "agent@example.com"
}

Is this a schema bug or did the API requirement change? The docs haven’t been updated.
