since it's a push notification, it uses WebSockets to notify the subscriber. That's why it will not be reflected on Clipboard because Clipboard represents the server's memory, which is not accessible from a client (without refreshing).
Thus, the only way to access the payload of a message is through JS.
But even though I created a JS function with several input parameters, I see that the callback does not push an event object to it.
Here's the callback's configuration:
Here's my JS function:
And here's the output in the console:
As you may see - nothing. Seems that "event" and "payload" are not keywords. If I leave it blank, also no effect. If I'd not provide it at all - again no results :\
Unfortunately, I was able to use the channel's properties only in the callback function. In it, I run a data transform, where I propagate the page with all content. Byt this DT, you could set all needed values on the clipboard and use it afterwards
