Hide feature in editor post

Hello,
I am using your plugin to post all news posts to Facebook.
Works great.
But, i have a multi author system and i do not want authors to hit the button. It should go automatically and therefore i want to hide the plugin for other roles ten admin when editing a post and publishing.
Of course the publishing on Facebook when a new post occurs needs to stay as a function on the background.
Can i hide this feature in de post edit screen voor other then the admin?
Thanx
