Page not found after successful Deploy and Publish

I am deploying a React app and the deploy is successful and ‘Site is live’, however I still get ‘Page not found’.
After reading other support tickets, I have discovered that the build does not have an index.html in the root of the project, though I’m not sure how to rectify this.
