Runtime Import Operations with the LIDAR Point Cloud Plugin

I am using the LIDAR Point Cloud Plugin and I want to import pointclouds in runtime. Importing pointclouds in editor via drag&drop works just fine, but none of the operations to import or create pointclouds in runtime, as shown here https://pointcloudplugin.com/buildin…oint-cloud-v06 , work for me. When I try it with Blueprints, depending on whether I check “use async” it either fails or the progress is always zero. I’ve already tried this with test files/arrays which only contain a few points.
When I try it in c++ it fails to recognize any of the required #include statements.

What am could I be doing wrong?
