How should I store user phone book contacts in Nakama?

Hello There,
We are working on social game where we are accessing players contacts list/ phone book so we we can recommend friend when user from contacts list joins.
Each user will have his own contact list which we would be updated. Can any one please let me know best way to save contacts details in the Nakama? Should we do it under user profile meta data or should we save it in storage engine?

Hey @YoursTruly you should store it in the storage engine because all user profile metadata is public.


Okay got it, thank you.
@lugehorsam Can you please let me know social graph for server friend recommendation feature? I couldnt find any documentation for it.
