How to link to wordpress plugin from reactJs wordpress theme

I have a basic reactJs theme setup in wordpress, which uses the WP API json, to display posts.

This works fine, however, is there a way I can link to a page template on my wordpress php site? I would like to use a wiki plugin, the easiest way I can think of doing this is to link to a static page template with the plugin installed.

My react theme uses routes, when I try and browse to the url slug that the plugin is installed on, it appears blank:

Is there a way to do this?

Any advice much appreciated.
