How to add leaderboard / game center to BB 1.3.6?

I've put in my leadboard info, but can only locate the options for Game Services. To my understanding, this was for Google Play. Will this work on iOS or are there different steps to follow?

 

game services is for both android and ios.. just place a leaderboard button and select game services and you're good to go.

 

but @drew where do u put the credentials for it ?

 

Thank you @tweettopix - where do I get it from ?

 

when you open the settings, you can leaderboard ID field, you can put it there.
