No documentation for creating associated record from grape entity documentation

Hi I don't know how to create an associated record from grape entity for. eg. I have two model Event and Setting and their relation is like event has_one: :setting and setting belongs_to: :event . Now while creating event using

 desc 'Create an event.' ,{
     params: Entities::EventEntity.documentation, type: :create
  }

My entity class is

module Entities
  class EventEntity < Grape::Entity
    expose :id
    expose :name, documentation: { type: String, desc: "Event name", required: true}
    expose :setting, using: Entities::EventSettingEntity
  end
end

and event_setting_entity is

module Entities
  class EventSettingEntity < Grape::Entity
    expose :id, :event_id
    expose :type, documentation: { type: String, desc: "Type" }
  end
end

I am able to create event using documentation but for setting how do I show field for setting. There is no documentation provide for this. Help me please. Thanks

No files, tests, or entry points are named in the issue. Start by reviewing the existing entity documentation guidance and the Event/Setting examples provided; document how associated setting fields should be represented during event creation, with a complete example that lets a newcomer determine the request shape.
