Setting config from middleware

1

Hey, i have middleware like this, to authenticate user via JWT, and question is how to modify config array with data stored in $decode variable. Is it possible?

    $app->add(
        function (Request $request, Response $response, callable $next) use ($config) {
            $input = $request->getParams();
    
            if (empty($input['token'])) {
                return $response->withStatus(401);
            }
    
            try {
                $decoded = \Firebase\JWT\JWT::decode($input['token'], $config['jwt_key'], ['HS256']);
            } catch (\Exception $e) {
                return $response->withStatus(401);
            }
    
            return $next($request, $response);
        }
    );
