Online Leaderboard

I want to add an online leaderboard to my mobile game, where players have to login to see their global ranking. How do i do this?

There was a previous network extension, but now it’s separate . What u develop is user side development, but for that I think simple server side development should be fine. I’m new but I researched enough, don’t do it if u r looking for no code service. It might come soon tho
