Custom interface in extension bundle

Hello,
I’m really struggling getting my extension working with directus 11.6.1 .
I’m using npx tasks to do all the necessary scaffolding and I now have an extension that loads correctly in directus (I can see it in the Settings->Extensions panel).
The problem is that when I try to add a field (an alias) that should use my custom interface (that for the moment is a simple warning message just for testing), the following happens:

  • The field is created in directus_fields table
  • The field is not showing up in my collection fields (differently from, for instance, adding a divider that shows up in the collection)
  • The field is not loaded in the collection detail page.

I can’t see errors or anything in the console.
Any suggestion?

I guess this is now solved, for some reason the extension was not showing up, but after restarting the application and reloading it I can see it.
