Very good question. From what I understand, there’s a special traversal link built and it’s all “built-in” and uses the CSS of the remote destination or something like that. 
<div><br>
</div>
<div>I’ve read absolutely zero docs about this. This is all based on a quick convo I had. I had the same worries and if I recall correctly, my worries were somewhat alleviated. </div>
<div><br>
</div>
<div>However, that being said, there is only one template in control hub, so if your user needs a different setup on their remote destination (or something like that) you need to go make a manual change. </div>
<div><br>
</div>
<div>It’s sorta like how there’s only one licensing template in control hub for new users. We’re gonna struggle with that. We might have to engage (professional) services which make uses of APIs to assign different services for different users in webex. But
 I digress. </div>
