I can't find BP network tutorial's offical demo in my disk

I am watching Offical Youtube Video 【Blueprint Networking】Introduction to Blueprint Networking - YouTube

I get trouble.They seems use some Offical Demo or map in their Video.
But I searched the folder and didn’t find the “network_features.umap” at all.

Anybody helps?

The map in the videos isn’t released yet, unfortunately. It will be added to the Content Examples project in the future, but we still need to do a little more polish and fixing before it’s ready to go out.
