Add google analytics integration to react app

Hi,

I have a Next.js react app which I would like Google Analytics integration for.

We don't need any custom events needed at the moment.
Just a pageview count and unique visitors and their location (essentially, everything that comes with the most basic integration.)

Access to the GitHub repository is provided. There is potential for more work in the future.

The aim is to get a basic integration in now to get basic stats on how many people are using the site. In in the future we will make improvements to our analytics.

I'm looking for someone who has experience in integrating Google Analytics with a React app.
