    # From https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#release
    # Note: The prereleased type will not trigger for pre-releases published
    # from draft releases, but the published type will trigger. If you want a
    # workflow to run when stable and pre-releases publish, subscribe to
    # published instead of released and prereleased.
    #
    # From https://github.com/orgs/community/discussions/26281
    # As a work around, in published type workflow,  you could add if condition
    # to filter pre-release attribute.
