Supabase in Preview environment

Hi, does anyone have a quick fix or best practice for creating an app with Supabase backend, including authentication, so that I can access all pages within the app in the v0 preview environment? I cannot login while in the preview environment because there is a failure in initialising the Supabase code so I cannot see any changes made by the LLM until I deploy to the public environment. Obviously I don’t want to deploy every time the LLM is prompted to make changes to the code. Sorry if this is a really basic question.
