Online leaderboard

I am looking online for a tutorial for an online leaderboard, but I am stuck. I am trying to make a board in my map where it shows off the top players with the most kills within their lifetime of playing. Any help / guides ? This link is the closest that helped, however does anyone have the code / guide, thanks. https://dev.epicgames.com/docs/game-services/leaderboards#accessing-leaderboard-information

Hey! Unfortunately with the current state of UEFN we aren’t able to retrieve player data in a way that would make an automatic leaderboard feasible.
That said, the closest thing we have is to create an in-game board and manually add scores based on user submitted screenshots via an external resource like discord.
