`registry_package` trigger and Github and ghcr.io

Hi, I would like to trigger some deploy workflow each time a new package get published to my Github Container Registry.

I am pushing manually some packages locally using a PAT with permission to manage the containers (as stated here).

I am trying to get another repo called when pushing to the registry, my workflow code looks like this:

name: Test Registry packace

on:
  registry_package:
    action:
      - published
      - updated

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: greeting_user
        run: echo hello

But this never gets triggered, any idea how to solve?
