How to paste a workflow into a Topic is not clear until after you’ve done it. As a result, we get a lot of hard to read JSON formatted workflows from new people making it less likely they will get help.
My suggestion is to:
Change the text message you get when you hover over the Preformatted Text icon in a way that makes it clear how you paste a workflow.
OR
Add some text in the blank Topic Editor template that clearly explains what to do.
