Unreal Engine 4.19 Released

New: Proxy LOD System (Experimental)

I’m really into checking this out but I cant seem to find it. I’m sorry if this has already been explained, but the directions say:

"From the Hierarchical LOD Mesh Reduction Plugin, you should be able to select the new module “ProxyLODMeshReduction”

For me there is only simplygon and search marketplace. I have searched the marketplace I dont see anything like ProxyLODMeshReduction as a plug in to download. Anyway, where do I download the plugin/module?
