I have a Vue JS project using Nuxt JS and am using the Vue Gtag library, i've recently migrated to Google Analytics 4 and have configured my $gtag event to fire some events with some data.

However, Google's new implementation means that the Event count isn't unique and there's no unique column that I can find for this, so how can I generate my own unique event much like how the universal google analytics does it by modifying my JS?

app.$gtag.event(`fudge_custom_events`, {
  'event_category': `Conversions`,
  'event_action': `Buttons`,
  'event_label': 'Sign up'
})
