There’s no integration between Community Store and Macareux’s Stripe Subscription add-on (that I’m aware of). The serve quite different purposes.
This old comment here still applies:
The main thing I’d emphasise is to look at subscriptions as their own process and management, and not an extension of a shopping cart.
One potential quick solution is that you use Community Store to manage the display of your products, but you turn off the cart and checkout. Then, you create a simple link between the product (maybe using an attribute) and a pre-configured Stripe subscription link - Create a payment link | Stripe Documentation
