If you have any questions for these apps, you can contact the third-party developer directly by using the information listed underneath the “Support” section of the app’s page.
Alternatively to an app you can also hire a Shopify developer and custom code it in your theme which, in some cases, can be a cheaper/more viable solution. It all depends what exactly you’re trying to achieve both design and functionality wise.
