How do I use the Layout Widget without a Listing ID? (data-id="LISTING_ID")

I’m referencing this page: Layout Widgets | Manifold for Developers | Manifold Docs

When trying out this widget on my website, I realized that my chosen token doesn’t have a listing ID, because it was never listed. I minted and transferred it to a giveaway winner.

Is there a workaround for this? It seems like all widgets rely on having a listing id to utilize them.
