Hello @felipegranado 
That’s precisely what we covered in our new Stripe mini-course: https://youtube.com/playlist?list=PLvTqMLG5UNf6sirvG9MaWbUeN1DlH3eWg&si=QpAWI5nlgk4pM3Hh
Using the elements of the Checkout page won’t change your issue though. Creating a subscription can only happen through webhooks (which are covered in the course), and need a backend like Xano to work. Frontends (like WeWeb) can’t receive webhooks as they are not servers.
