We created a Power App with an accompanying Dataverse. I need to delete the test data from all the custom tables used by the application to get ready for production. The only articles I could find online directed my to the Data Management section of Dynamics 365, to create a bulk delete. However, this interface seems to show only the Dynamics tables and not the custom tables here:

If someone can tell me how to truncate the dataverse tables, I would appreiate it.
