Hello,
The vendor don't have to configure anything in the plugin.
But you need to publish the "market" version of the Stripe Connect plugin which will add a button in the vendor edition profil ; it will allow the vendor to "connect" his Stripe Account with your store.

By the way, do not send me private message, use the "contact us" form instead.
