    <strong>Note:</strong> The <code class="bg-white border border-gray-200 px-1 rounded">usage</code>
    key is referenced in code (e.g. <code class="bg-white border border-gray-200 px-1 rounded">process_by_system</code>
    is used by the PJ cron job). Users with a usage key are protected from deletion.
    To delete, remove the usage key reference in code first.
