    def initialize(current_user:, container:, **args)
      @current_user = current_user
      @container = container
      @is_super_sidebar = false

      args.each do |key, value|
        singleton_class.public_send(:attr_reader, key) # rubocop:disable GitlabSecurity/PublicSend
        instance_variable_set("@#{key}", value)
      end

      @route_is_active ||= ->(_) { false }
    end
