Missing "Approve and Run" button

I am an admin on a repo that an external contributor has just contributed a Pull Request to: https://github.com/The-Peoples-Pantry/website/pull/490

Actions were not run against their Pull Request by default since they’re a first time contributor, but now I have approved their PR and I’d like to run the actions. I’m following the advice on Approving workflow runs from public forks - GitHub Docs but I’m not seeing the expected “Approve and run” button on the workflow:

Under the Actions Permissions settings for the repository I’ve selected:

  • Allow all actions
  • Require approval for all outside collaborators
  • Read repository contents permission

Based on the advice in the linked article, this seems like a bug to me and I should be able to see a button to approve the Pull Request and run the associated actions.
