Github action not triggering on pull request

I’ve made a PR to a repo adding workflows. (ci: add a check for wordpress coding standards by nishantwrp · Pull Request #146 · creativecommons/wp-plugin-creativecommons · GitHub). But the action didn’t trigger. Can someone please tell me what could be the reason or if I’m doing something wrong?

The push event won’t run (within your fork) because you’ve configured it to run only for pushes to master. Also you may need to enable Actions on your fork if you haven’t already.

I’m not sure if pull_request events run if the target repository doesn’t have actions enabled yet. :thinking:
