What permission is essential to view detailed information about flow test runs?

To view detailed information about flow test runs, the permission that is essential is the ability to 'View All Data.' This permission grants users comprehensive access to all records in the organization, which includes insights into flows, their test runs, and the related data involved in those runs. Understanding the detailed execution of flows, including variables and debug logs, requires extensive visibility into the records processed by those flows.

While other permissions, such as 'Manage Flow' and 'Run Flows,' relate directly to flow management and execution rights, they do not provide the full level of data oversight required to look at the intricate details of flow test runs. Similarly, 'View Setup and Configuration' allows for visibility into system settings but doesn’t extend to granular data access.
