Configuring WSGI to service a single index.html file for a single page application

I have a standard Django application set up using WSGI on Apache2 (Ubuntu 18.04)

I now want to serve all front end content via a single index.html file (still allowing access the /admin url and ensuring the REST api calls via /api work). I'm using Ember for the single page application.

Any help much appreciated!

Here is my current .conf set up:
