Highlighted content Filter By Document Library

Hi,

   I would like to make a Highlighted content whihc is filtered by a specific document library.  I assume that this would be the Managed Property ListId.  

   But when I puth the list ID of the library is, the filter is blank.  As a list ID I have tried

• Library Name
• Library GUID with {}
• Library GUID without {}
• Library GUID with {} as HTML
• Library GUID without {} as HTML

Any advice on this is appreciated
