How can I know the LiveView is child LiveView if that is sticky?

It can be recognized if the LiveView is not sticky by checking that a socket of LiveView has parent_pid.
But if it is sticky, I can’t find a way to recognize whether the LiveView is a child LiveView or not.

I checked nested_render/3 function in Phoenix.LiveView.Static.

defmodule Phoenix.LiveView.Static do
  # Holds the logic for static rendering.
  @moduledoc false

  alias Phoenix.LiveView.{Socket, Utils, Diff, Route, Lifecycle}

  # Token version. Should be changed whenever new data is stored.
  @token_vsn 5

  def token_vsn, do: @token_vsn

  # Max session age in seconds. Equivalent to 2 weeks.
  @max_session_age 1_209_600
