payment formula and subscription

Question:

Hello, I created subscriptions on my wix studio site. The subscriptions are active, the payment methods are configured but I can’t add a page or section for customers to reserve their subscriptions. Do you know please how to add a subscription section on your site?

Product:
Wix Studio Editor.

What are you trying to achieve:
I would like to add a page for purchasing my subscriptions on my site

What have you already tried:
I used the wix help blogs but it only says how to create formulas or how to add them to our site with Wix Editor and not with Wix Studio

Additional information:
I was able to observe that the subscriptions appear when I create my mobile application linked to my reservation site.
