How to get the user who manually triggers a workflow (workflow_dispatch)?

Long story short, we are automating release notes which is created from a manual workflow (with workflow_dispatch). Is there any way to get the user name who does it, so that in the release note we can add something like This release has been created by XXX on MM/dd/yyyy?

The information generated by GitHub is like github-actions released this 17 hours ago, which is not very useful.

I think, in the workflow, you could pull it out of the github context object using ${{ github.actor }}
