Open Api Specs problem

Hello Fellas,

I am trying to use Open API Spex but as off this point with not much success.

I have been trying to define my schemass like following:

defmodule UserInstrument do
        
    OpenApiSpex.schema(%{
      title: "UserProfile",
      description: "Just a user profile",
      type: :object,
      properties: %{
        level: %Schema{type: :string, description: "The level of the user for the particular instrument"},
        instrument: %Schema{type: :string, description: "The musical instrument name also unique idendifier for the instrument"}
      },    
      required: [:level, :instrument],
      example: %{
        "level" => "V0",
        "instrument" => "piano"
      }
    })      
  end       
            
  defmodule UserProfile do
        
    OpenApiSpex.schema(%{
      title: "UserProfile",
      description: "Just a user profile",
      type: :object,           
      properties: %{
        email: %Schema{type: :string, description: "The user email"},
        id: %Schema{type: :integer, description: "unique identifier"},
        instruments: %Schema{type: :array, items: UserInstrument}

      },
      required: [:email, :id, :instruments],
      example: %{
        "id" => 12,
        "email" => "someemail@server.com"
      }
    })
  end

end

But somehow when I generate the schemas swagger fails to pick up the relationship between user profile and the instrument. This is also a problem when I am trying to do schema testing in my rest responses.

Am I missing something here ?
Or is this a bug of the implmentation library ?
