| # Currently there is no way to get the pull request number from the event payload in a workflow_run event. | |
| # We save it in the 'test' workflow. | |
| # This first step extracts it. | |

| # Current limitation: | |
| # As of 2023-05-18, https://github.com/actions/download-artifact cannot download artifacts across workflows. | |
| # As a result, have to use the script GitHub provides to download the artifact. | |
