Do I need multiple Stripe accounts if I have multiple sites?

I’ve just handed over a site with ecommerce to a customer.
The customer already has another site with a store that I’ve designed and handed over to them.

To my big surprise, it seems like it’s not possible for them to connect the same Stripe account to the second store?

Is the solution to create another Stripe account, does that make sense? I know very little about Stripe.

Thx
