Sandbox testing with stripe test mode

Hey folks Im just wondering if theres any guidance on how to connect a bank feed in the sandbox to a test mode stripe account so I can test my invoicing flows locally.

Im able to create invoices ok but I cant figure out how I enable a ‘bank feed’ to then connect stripe.

When I enable a bank feed I can only see the NatWest logo and when I click I get taken to a page with services but there are none listed
