Nbdev: code-fold equivalent for code output

I understand #|code-fold: true collapses code into a dropdown, but is there a way to do this for code output? I have code that prints a long string and hoping to not have that initially populate when viewing the page.

Thanks in advance!

The quarto docs reference an ‘output-folding’ extension, but it seems to just be a made-up example. I can’t actually find it anywhere.
