tinymce adding a context form to a custom plugin in wordpress

Question

So after a lot of trial and error I managed to make a simple tinyMCE plugin that suits a project I'm working on , the plugin at the moment adds or removes a html tag from the slection , but now I want to add a Context Form similar to the link Context Form tinyMCE comes with but there is no clear documentation to do this with the wordpress plugin inside the tinymce.PluginManager . Anyone know how to add this using the tinymce functionaities (in Wordpress).
