When is the IPlacementModeModule Loaded?

I have created an Editor Module and I want to access IPlacementModeModule Functions in order to Register Category into Place Actors tab.

problem is the IPlacementModeModule::IsAvailable() is never true it seems that my module is loading before PlacementMode. I have Tried changing the laoding phase to PostEngineInit and PostDefault but the PlacementModeModule is still not loaded at the time of My Module’s Startup call.

Solved: Use PostEngineInit Loading Phase and manually Load the PlacementMode Module using ModuleManager In the Startup function.
