Hello @paztek, How can I use ConfigService instead of hard coded values. I like to use useClass instead of useFactory

// ....
        BaseCacheModule.registerAsync({
            useFactory: () => {
                return {
                    store: redisStore,
                    host: 'localhost',
                    port: 6379,
                }
            },
        }),
// ....
