Point cloud and object interaction in Meta Quest 2

I am trying to build an application for the Meta Quest 2 where I have a 33 million point cloud of a building and I need the player (avatar) to interact with it and other object that I keep there. I have successfully imported the point cloud but I am facing issues with the placement of objects in the point cloud as it seems I need to maintain the axes of both to make it seem like the real world. I would appreciate any suggestions on how I can perform the scaling and aligning the axis to make it seem like the real world. Thank you.
