Get list of ns in a rancher project

Is there a way to get a list of all ns assigne to a rancher project using rancher2-provider data sources?

I found kubernetes_all_namespaces to get all ns. As the project id is an annotation in the ns, one can grab that info. Below will create a map with all ns, which are assigned to a project

data "kubernetes_all_namespaces" "allns" {}

data "kubernetes_namespace" "ns" {
  for_each = toset(data.kubernetes_all_namespaces.allns.namespaces)
  metadata {
    name = "${each.value}"

locals {
  ns = {
    for key,value in data.kubernetes_namespace.ns : 
        projectid = lookup(value.metadata[0].annotations, "", null)
      if (lookup(value.metadata[0].annotations, "", null)) != null
