Workbench Insights not showing

Hi, we are currently transitioning from Sources to Payment Methods API, and we intend to use themigration tool as advised in this guide: Reusable object migration from Sources to Payment Intents : Stripe: Help & Support. I am am trying to test it on my test account but I am not seeing the Summary/Insights Workbench tab there. What could the reason be? I do have Source pds and charges made with them. Thanks!
