Allow anonymous user to export spaces and pages using Content Exporter Add-on

[Mugove Machaka]

I'm a site admin and I installed Content Exporter from marketplace. I want to allow anonymous users to export spaces and pages using Content Exporter Add-on into PDF rather than them using default exporter but the option to export using Content Exporter is not available for anonymous users. As an admin I can export using that add-on but an anonymous user can't get the add-on functionality? Any help?
