Is there a way to "return" a value from a workflow?

Is there a way to “return” a value from a sub workflow? Suppose I have a sub workflow that creates a db record and I need to access this record ID in a downstream job in the parent workflow. Here’s an example I have that attempts to recover it through recorded values but with no success:

defmodule ChildJob do
  use Oban.Pro.Worker, recorded: true
  
  alias Oban.Pro.Workflow
  
  def workflow() do
    Workflow.new()
    |> Workflow.add(:child, new(%{}))
  end
  
  @impl true
  def process(job) do
    {:ok, "secret_id"}
  end
end

defmodule ParentJob do
  use Oban.Pro.Worker, recorded: true
  
  alias Oban.Pro.Workflow
  
  def workflow() do
    Workflow.new()
    |> Workflow.add_workflow(:a, ChildJob.workflow())
    |> Workflow.add(:b, new(%{}), deps: :a)
  end
  
  @impl true
  def process(job) do
    Workflow.all_recorded(job) |> IO.inspect()
    :ok
  end
end

iex(3)> ParentJob.workflow() |> Oban.insert_all()
%{"b" => nil}
