Properties of objects are not shown

Hello
The swagger ui page doesn’t show the parameters of objects when editing. Is there a way to add them?

My code:

register_rest_route( $namespace, '/' . $path, [
		  array(
			'methods'             => WP_REST_Server::EDITABLE,
			'callback'            => array( $this, 'proccess_request' ),
			'permission_callback' => array( $this, 'get_items_permissions_check' ),
			'consumes' => "application/json",
			'args' =>  array(
				'request_id' => array(
					'validate_callback' => function($param, $request, $key) {
						return is_numeric( $param );
					},
					'required' => true,
					'type' => 'integer',
					'description' => 'Your internal request id',
				),
				'object' => array(
					'validate_callback' => function($param, $request, $key) {
						return "products" === $param;
					},
					'required' => true,
					'type' => 'string',
					'description' => 'The object type to run the call against.',
				),
				'total_count' => array(
					'validate_callback' => function($param, $request, $key) {
						return is_numeric( $param );
					},
					'required' => false,
					'type' => 'integer',
					'description' => 'Total count of the products',
				),

				'data' => array(
					'type' => 'array',
					"items" => array(
						"type" => "object",
						"properties" => array(
							'action' => array(
								'required' => true,
								"type" => "enum",
								"enum" => array(
									"add", "update"
								)
							),
							"date_created" => array(
								'required' => false,
								"type" => "string",
							),
							"date_last_modified" => array(
								'required' => false,
								"type" => "string",
							),
						),
					)
				),

			 ),

		  ),
		]);
