How does the content preview works? I cannot find any documentation refering to this feature.

EDIT: I just found out this: [https://github.com/agentejo/cockpit/issues/782](https://github.com/agentejo/cockpit/issues/782)  
And it worked for me, but would like to know more about it, specially the websockets version of it.
