Point Cloud preview

[AugmentedRealityCat]

In the doc it's written:

The point cloud generated from the text/image will be shown in this screen. You can select the point cloud to regenerate the mesh with different methods/parameters.
https://github.com/Firework-Games-AI-Division/dmt-meshes/blob/main/docs/MESH_GENERATION.md

I had the impression at first that this meant the point cloud would appear here as an actual image preview, but in reality it's only a text window exposing a list of what looks like hash codes to identify all the point clouds you have generated so far. The latest is at the top.

Is there any way to see what the point cloud looks like before generating the mesh ?

Also, is there any way to clean that cache of point clouds, or at least the list ? EDIT: I found that I could simply delete all the files in the (...)\Blender Foundation\Blender 3.3\3.3\scripts\addons\dmt_meshes\data\pc folder to clear the cache. There might be a cleaner way, but this works !
