How to find out if the Github Actions event that triggered the current workflow is a new pull request?

Question

I have a Github Actions workflow that fires on:

on:
  pull_request:
    types:
      - synchronize
      - opened

that runs my custom action:

jobs:
  my_job:
    uses: "org/repo/.github/workflows/main.yml@master"

In the action org/repo I want to do an additional thing when a pull request is opened, but not when it is synchronized. So in org/repo/.github/workflows/main.yml I do:

- if: ${{ condition }}
  name: Do that additional thing

What should be the condition to differentiate between a newly open pull request event and a "synchronize" event (pushing new commits etc)? I guess that would involve checking something in ${{ github.event.pull_request }}, but I couldn't find it in the documentation.

The condition is:

- if: ${{ github.event_name == 'pull_request' && github.event.action == 'opened' }}

Your answer could be improved by adding more information on what the code does and how it helps the OP. – Tyler2P Sep 18 '22 at 17:56
sorry but it covers also the "synchronize" case? – Maurizio Cacace Mar 22 '23 at 11:04
