Setting the "by" field on a custom ui dashboard gadget

Hi all - this is probably an obvious question, but I don’t see an answer in the docs or forums. When one creates a Custom UI Forge app for a dashboard gadget, how do you set the author that shows up when you click on the Edit dashboard → Add a Gadget window? It’s the yellow section in the below screenshot. The text below the field seems to come from the “description” field in the manifest.yml, but I don’t see anything in the docs.

  jira:dashboardGadget:
    - key: my_test_key
      title: My title
      description: A hello world dashboard gadget.
