Need PNP Search results webpart to display metadata column that I added in a SharePoint library

Hello vassp1980 

1. map your column to a managed property, here are more informations:

In PnP add the property in page 1 under selected property and use it for more configurations.

2. Set permission on your documents, a search is secuirty trimmed, a user can only see document, he has access.

2.b. Or use a UserProfile property and show documents, when the property will be match with the metadata from the document.

Best, Dave
