  def handle_request(request)
    case request.method_name
    when 'MethodOne'
      # Handle MethodOne
      req = MyPackage::MethodOneRequest.decode(request.payload)
      resp = MyPackage::MethodOneResponse.new(...)
      Spikard::Grpc::Response.new(payload: MyPackage::MethodOneResponse.encode(resp))
    when 'MethodTwo'
      # Handle MethodTwo
      # ...
    else
      raise "Unknown method: #{request.method_name}"
    end
  end
