No Autopost Plugins listed

We're trying to setup Autopost for Twitter, however no plugins are listed. Reinstalled JFB and checked Joomla plugin for autopost but nothing is listed.

What step are we missing?

UPDATE - Enabled "Open Graphc" plugins to show Autopost options.

However we cannot find this setting in our JFB, as per documenation "First configure an Open Graph object in the JFBConnect backend > Open Graph > Objects configuration area and then select it in the Channel's Autopost Objects section."

 

Thanks Melissa, does JFB allow to customize the message before its posted? IE adding hashtags to Twitter.
