How to add metadata to an online subsystem session?

Hello,

How does one add metadata to a session via blueprint? I’m currently working on an online game and I want to store data such as the map name, server password, and other things. But unfortunately, probably due to my own ineptness to properly comb through documentation, I’m unable to find exactly how I’m supposed to do this…

I basically want to do the equivalent of this (this code isn’t mine, I avoid C++ because I’ll break something if I even dare glance at an IDE):

FOnlineSessionSettings SessionSettings;
SessionSettings.Set(TEXT("MapName"), TEXT("DesertArena"), EOnlineDataAdvertisementType::ViaOnlineService);

Any advice is appreciated!
