I am trying to extend the discourse UI by leveraging the plugin-outlets. Currently trying to add a custom header on top of the discourse header by leveraging ‘above-site-header’ plugin-outlet. I would like to make this template dynamic based on the logged in user. I am not able to figure out which ember controller backs up the plugin-outlet templates. I would really appreciate if someone could point me in the right direction on this one. (I tried ApplicationController as the outlet sits in application.hbs, but no luck).
