How to call OverlapBlockingTestByChannel from a python script (or another way to test overlap)?

Hi all!

I’d like to call OverlapBlockingTestByChannel from a python script. I saw that this method is not exposed in the python API so I thought that the following would work:

world = unreal.get_editor_subsystem(unreal.UnrealEditorSubsystem).get_editor_world()
world.call_method("OverlapBlockingTestByChannel", *args, **kwargs)

But then I get

Exception: World: Failed to find function 'OverlapBlockingTestByChannel' on 'World'

I was wondering if this is possible or whether there is another way to test overlaping in python. My goal is to check if a box of space in my level is not occupied to spawn an actor there.

Thank you very much!
