LGTM! 🚀
Although I'd be interested to know why so many tests failed for a workflow-related change.

[Molter73]

@Maddosaurus, we kinda broke OSCI yesterday, sorry about that. We are working to get it back up and running and it is unrelated to these changes.

[Molter73]

Could we unify this workflow with https://github.com/stackrox/collector/blob/master/.github/workflows/add-issue-to-triage.yml? Their goal seems to be pretty much the same, add issues/prs onto the OSS board.

[tommartensen]

@Molter73 - good idea, but while the goal is the same, we only want to add only external Pull Requests. The first job of this new workflow is the filter for that. We would need to implement another condition into that to distinguish between issues and PRs. I think it's cleaner to have separate actions for each type of input.

You can ping me in the PR when I can rebase or re-run tests. Right now Merging is blocked.

/lgtm

[Molter73]

@tommartensen you should be able to merge now, it was blocked because we require an approval from someone in the collector-team before merging.
