How can I issue a download request at runtime?

I’m having a hard time finding a solution on how to download a file from a remote server (e.g. www.example.com/example.pak) during runtime.

I’ve been reading the API reference and I came upon FCloudFile (https://docs.unrealengine.com/latest/INT/API/Runtime/OnlineSubsystem/FCloudFile/index.html)
From the remarks it says that it holds the data used in downloading a file asynchronously from the online service.

But I cannot find a function that has a download url as a parameter then executes an asynchronous download and later on yields an FCloudFile.
