How do I enable/disable GameplayDebugger categories in Simulate mode?

We are using the new GameplayDebugger system, which doesn’t seem to create a GameplayDebugger actor at runtime. Without a GameplayDebugger actor, how can I enable/disable categories in Simulate mode? I figured out how to enable my custom category by default in both normal and simulate modes, but I would like to allow designers to enable/disable it at will. Ideally, there would be a handy settings window that you could open to manage this stuff in the editor, but I can’t find anything like that.
