Existing stripe account

When i go to connect stripe it opens a popup window with stripe set up instructiosn but i can’t find what to do if my client already has a stripe account. I’m assuming there should be a way to connect an existing stripe account but can’t see it - can any one help as i don’t wnat to tell the client they need to create a new stripe account.
