How to send data to Segment from a Vue/Nuxt app?

Question

I'm trying to connect to a Segment source from a Vue/Nuxt application. I'm using the @dansmaculotte/nuxt-segment npm package for Segment setup.

Here's the code:

nuxt.config.js

config = {
  //...
  modules: [
    '@dansmaculotte/nuxt-segment'
  ],
  segment: {
    writeKey: 'SEGMENT_WRITE_KEY',
    disabled: false,
    useRouter: true
  },
  //...
}

component.vue

this.$segment.identify('***', {
  name: '***',
  email: '**@**.com'
});
this.$segment.track('***', { plan: '***' });
this.$segment.page('***');

Segment setup:

On the deployed app, Segment is being initialised and does make tracking calls successfully.

But with all that, the data does not come through on Segment. I didn't get any errors that can tell me what's wrong. Not sure what the problem is. Thanks in advance for whoever might be able to help.
