Is it possible to pass a map to args instead of a list of attributes in code_interface?

I'd like to pull off something like:

actions do
  update :update_stats do
      argument :stats, :map

      Enum.map(arg(:stats), fn {key, value} ->
        change set_attribute(key, value)
      end)
    end
end

actions do
  update :update_stats do
      argument :stats, :map

      Enum.map(arg(:stats), fn {key, value} ->
        change set_attribute(key, value)
      end)
    end
end

code_interface do

    define :update_stats, args: [:stats]

  end

code_interface do

    define :update_stats, args: [:stats]

  end

but I get the following error:

Compilation error in file lib/leaderboard/data/resources/wallet.ex ==

Is there a way to dynamically pass in args that you want to update on the resource? Or do you have to hard code the set_attributes? I'm trying to bypass the need to pass in each attribute in order every time. As their are many attributes and not all of them will be updated each time.

Is there an example of defining a resource that is an external API that you are querying from?

I'm trying to wrap my head around modeling a resource that is an external API. Should you even do that?

How do I make an attribute on a resource unique?

I believe Identities are the way to do it https://ash-hq.org/docs/guides/ash/latest/topics/identities But having trouble finding code examples.
