Could you add a test account in https://demo-accelerator.litium.com/ for a B2B user?
I have received the question from several of us at Columbus who need to create a new user every time for tests and Demo, as the environment is cleaned every night.
Would you be able to create a B2B user with a business connection that you can use for testing?
The public demo-site are updated with the B2B order flow, see https://docs.litium.com/partner/demo
