Flexicontent & JO Auto Post Facebook

Hello,

I regularly use the plugin "JO Auto Post Facebook" on regular sites to publish directly on a Facebook page an article written in the back office.
This one does not seem to work with Flexicontent, and it is not visible in the list of plugins at the level of a category or type of content.
Do you have any idea that this plugin can be used with flexicontent?

thanks !
