How is the best way to implement Achievements in Ludei?

Hi C2 fellas! ^^

I'm trying to implement a Achievement system in my game on Google Play and it was compiled in Ludei/CocoonJS, then I wonder what is the best way to do this: using the plugin Cocoon or Google Play in C2?

Thank you in advance the attention and collaboration.

UP! (in other words, S.O.S.)

Google Play already manages achievements so you could use Google play

Thanks, MadSpy!
