Question: Orchestration v20.4.1 - How to delete an AD Domain User from Orchestrator?

I can’t seem to delete individual AD domain users I’ve added to Orchestrator v20.4.1. I recently added an AD Group as the path into Orchestrator and was hoping to remove individual accounts from Orchestrator that as also members of that AD group. I’m attempting to do this as the “admin” account within this Tenant. These accounts are in an added Tenant (not Default).

But, the Delete button in user management is grayed out and the “Remove” sub-menu for these accounts is also grayed out.

I’m hoping I’m just missing something.
