OSX with Qt3D 5.12.2 and QML, SceneLoader: Found no suitable importer plugin for 3ds obj

[vityafx4]

I installed the most recent version of Qt5 - 5.12.2 for macOS and tried to create an application with SceneLoader object for loading my scenes. It does not work no matter what format I pass to it, I always have this error:

Found no suitable importer plugin for <any format here>

I also can't find any examples in my /Users/user/Qt/Examples/Qt-5.12.2/qt3d (it is where I have Qt installed) regarding assimp but according to the documentation it must be there.

What have I done wrong? Do I need to install anything else in order to make it work?
