Configure ReactGA to track 11 events in a Create React App

I have a functioning, deployed CRA with no Router, just href #links. It is built with reactstrap and uses Stripe to process orders. react-ga is installed and currently configured to track new page views. I need to finalise the tracking to cover * clicks on 5 navbar links (href) * 2 CTA buttons (href) * 1 modal trigger * 1 link to external site from the modal * 4 buttons selecting product options * 1 button triggering Stripe payment * success or failure of the purchase * 1 link to external site from the footer The deployed SPA can be seen at [login to view URL] The source is accessible on GitHub and you will be provided with the Stripe test credentials. We want to start a marketing campaign as soon as this is done so a timely result is preferred.
