Find the `interested_users` table in the Supabase project and the frontend code where this data is displayed. Research Supabase Realtime subscriptions to listen for table changes. Implement the subscription in the frontend, likely in a Next.js page or component, and update the UI when new data arrives. Test that changes to the table trigger updates in the browser.
