You can connect your existing Stripe account.

From the Integrations tab in your Account Settings, click Connect next to the Stripe option. (Please note: only the account admin can configure the Stripe integration.)

During the setup process, if you enter the email address associated with your existing Stripe account, the integration will automatically create a connected account that is synced to that account.

You will be able to toggle between your connected account and your existing Stripe account from the top left corner of your Stripe dashboard.
