Facebook permissions

im trying to ling my leaderboards to facebook. the thing is i cant continue because i get this error : “It looks like you haven’t made any API requests to access content with the publish_actions permission in the last 30 days”.

this is the plugin i use. its for my android game.

the question is. how can i finish this last step ?

You need to make publish_actions calls.
You can give yourself permissions as the admin of the app through the Graph API.
