gtag set is not attaching data as expected

I'm trying to follow this guide: https://developers.google.com/gtagjs/reference/api#set

It says that you can use gtag('set', {key: value}) to add a set of values to the next gtag calls. However, it doesn't work.

So, this is the setup I used in order to have gtag available on the app:

window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('set', 'anonymizeIp', true);
gtag('config', 'my_ga_tracking_id', {
  send_page_view: false,
  custom_map: {
    dimension1: 'a_dimension' 
  }
});

And then this code once the app is loaded:

gtag('set', { a_dimension: 'test' });
gtag('event', 'an_event');

I expected to see the a_dimension attached to the event an_event sent to GA but I can't find it.

What am I missing?

I solved by using gtag('config') where I needed to set common dimensions instead of gtag('set').

The only think I dislike in this solution is that I need to have those common values always available at that level.
