    # enterprise_server_host allows joining from GitHub Actions workflows in a
    # GitHub Enterprise Server instance. For normal situations, where you are

    # enterprise_slug allows the slug of a GitHub Enterprise organisation to be
    # included in the expected issuer of the OIDC tokens. This is for
    # compatibility with the include_enterprise_slug option in GHE.

    # This field should be set to the slug of your Github Enterprise organization if this is enabled. If
