Channels element

Does anyone know how to show a channel element on a form?
Can’t find an example or documentation except for how to handle the channels.

What is a channel element?

In your documentation you have:
“// This will join a user to “chatRoom”
“action”: “channelJoinAnon”,
“options”: {
“channel”: “chatRoom”

So initially thought this is an element that adds a chat room.
I get that it’s not now but could use some more info and examples maybe…
