Scores Api with Facebook sdk 7.3 and Unity 5.3

Hi everyone. I’m trying to implement a scoreboard with the new facebook sdk 7.3. I’ve already made a script that works using Facebook sdk 6.x . Someone knows the new system with the LoginWithPublishPermissions and the new result system? Some hints? Thank you

I have downloaded friendsmasher demo and it has it all. but the LogInWithPublishPermissions with pubish_actions does not work for my project. for some reason I dont get pubish_actions granted for other users for scoreboard. I tried to ask permission from facebook, and they rejected my request because facebook claimed i dont need permision and LogInWithPublishPermissions with pubish_actions is enough. I dont get any error and can login with new persmission but pubish_actions is not in the token.
