Produce a map from the cartesian product of two lists to use with for_each on a resource with Terraform

I need to create a datadog synthetics monitors with the resource datadog_synthetics_test

I need to monitor multiples cluster, with multiple point of view :

# Clusters
variable "datadog_gke_clusters" {
  default = [
    # NPRD
    {
      name        = "cluster01"
      environment = "nprd"
      url = {
        private = "https://private.domain-priv.com"
        public  = "https://public.domain.com"
      }
    },
    # PROD
    {
      name        = "cluster02"
      environment = "nprd"
      url = {
        private = "https://private.domain-priv.com"
        public  = "https://public.domain.com"
      }
    }
  ]
}

# Point of views
variable "gke_slo_" {
  description = "Response time threshold in ms to respond to a request."
  default = [
    {
      zone              = private
      monitor_threshold = 50
    },
    {
      zone              = public
      monitor_threshold = 100
    },
  ]
}

for_each need a map or a list of strings

resource "datadog_synthetics_test" "gke-monitoring" {
  for_each = ... # cartesian product of lists

  type    = "api"
  subtype = "http"
  ....
}

There is a function [setproduct(sets...)][1] which produce a list which combine values of each list, but not a map.

I would need to produce a map which look like this :

  {
    "cluster01-private" = {
      name        = "cluster01"
      environment = "nprd"
      url = {
        private = "https://private.cluster01.domain-priv.com"
        public  = "https://public.cluster01.domain.com"
      }
      zone              = private
      monitor_threshold = 50
    },
    "cluster01-public" = {
      name        = "cluster01"
      environment = "nprd"
      url = {
        private = "https://private.cluster01.domain-priv.com"
        public  = "https://public.cluster01.domain.com"
      }
      zone              = public
      monitor_threshold = 100
    },
    # PROD
    .... etc
  }

How could I do that ?
