Pass EventData as a parameter in a CloudScript triggered via Prize Tables

I'm trying to create a delayed rewards window that shows up when a leaderboard finishes and the user has placed inside one of the specific reward tiers. To achieve this, I'm triggering a cloudscript function as part of the prize table which stores the reward tier. I'd also like to store his final leaderboard score and the leaderboard version. Looking at the raw event data, I see that a JSON container already exists which has this information embedded (named "TriggeringEventData").

I'd like to request having a boolean that , when checked, passes this data from a prize table to a cloudscript function as a parameter.
