Including non-standard resources in Unity HoloLens app

I'm building an app that must visualize a large point cloud on HoloLens 1st gen. As performance is an issue wit large clouds, I'm using Potree, an octree that takes care that only a preset number of points from the cloud are rendered.

The solution works in the editor, but, you guessed it, not when deployed on HL.

The point cloud in the Potree format is a set of couple of .json and hundreds of .bin files stored in hundreds of subfolders following the octree structure, all of that stored within a single folder, and the path to this folder is accessed by the renderer at runtime. However, I don't know how to include this folder in the HL app. Using Resources doesn't work as it's not really a standard resource. I've seen Asset Bundle suggested elsewhere, but according to this post asset bundling doesn't work on HL.

Is there a way to simply put this complex file structure in an accessible directory on HoloLens?

I feel completely stuck here and any help would be much appreciated.

Some of the things I've tried:

Unity 2019.4 HoloLens 1st gen

Using pcx needs to be adjusted to binocular rendering in publishing settings. Please uncheck "Enable Depth Buffer Sharing" in XR Settings, and change "Single Pass" to "Multi Pass", as shown in the figure.enter image description here

For anyone stumbling upon this - I ended up using Unity StreamingAssets and accessing the folder with Application.streamingAssetsPath - works beautifully!
