<p>While the AI agents module is enabled while adding/editing an AI assistant, the first field you will see is a select list "Use agent as assistant"</p>
<p>Per slack conversation:<a href="https://drupal.slack.com/archives/C0803LX4536/p1749020868928549?thread_ts=1749015523.730669&cid=C0803LX4536">https://drupal.slack.com/archives/C0803LX4536/p1749020868928549?thread_ts=1749015523.730669&cid=C0803LX4536</a></p>
<p>This should be a hidden field.<br>
