Write Leaderboard integer

Hey, I’m wondering how the write leaderboard integer works - how does it understand what leaderboard to write to?

The doc states ‘Writes an integer value to the specified leaderboard’ but the inputs don’t have anything to do with a specified leaderboard…?

Thanks.

Haven’t dug in too much about this, but is this function linked to UE’s logged in functionality? As in the ‘Show external login UI’ functions? I have no idea how UE figures out where to login here either, if it’s on PC for instance, how does it know it’s for e.g Steam - how do you specify this?

I’m right now mostly interested in Mobile platforms but would love to hear more about this generally.
