Configuring chat channels for advanced AI agents is no longer recommended.
Instead, consider <a href="https://support.zendesk.com/hc/en-us/sections/8264312886554">configuring messaging channels</a> or <a href="https://support.zendesk.com/hc/en-us/sections/8264365933210">configuring email channels</a>.

<br>
</li>
</ul>
</li>

<strong>Link Block</strong>

Max 3 "Link clicked" on the same level<br>
