Hi, I want to give rewards to players on the leaderboard based on their ranking. Rewards items are stored as JSON in player title data. The leaderboard resets once per week. When a player will log in, he has to see a pop-up with rewards and the place that he achieved. I tried to use the price table to run the cloud script, but how can I receive the player rank of this leaderboard? How should I implement the whole system?
