Question about User Lib

Not sure what I’m doing wrong. I went to add a Jotform to my page, so I got the script code from the Jotform website and I pasted it into the place in the List panel that says INSERT CODE. This caused a draggable component to appear which I was able to drag into the page, and viola, my form appeared. But how do I get this snippet into the User Lib, so I can drag it again to another page in my site?

In the documentation, it shows a heading titled SNIPPETS with the words User Lib in orange, but I do not see this in the Library Panel, nor can I figure out how to make it appear. Any help would be greatly appreciated.
