MongoDB Batch to BigQuery not running on the specified machine type about dataflowtemplates HOT 1 OPEN

So after some digging around I found this in the dataflow_job.tf

variable "launcher_machine_type" {
  type        = string
  description = "The machine type to use for launching the job. The default is n1-standard-1."
  default     = null
}

variable "machine_type" {
  type        = string
  description = "The machine type to use for the job."
  default     = null
}

The launcher_machine_type is a parameter I can't find a way of defining either in the Cloud Shell or in the console, and I would assume is the reason for the job to always default back to the n1-standard-1 machine type instead of the machine I'm specifying in the workerMachineType-parameter.
