How to know if is multiplayer a game in UE4 blueprints?

Is there any node that tells you if the game it’s a multiplayer game, so I can do A or B? thanks.

I think it’s this…ode/index.html.
P.S. Can’t find it in blueprints.

Oh well, easy HACK** get all player controllers in the game.
Count them if more than 1 do that or else…
