Getting top users for an item

We have an use case where we need to get top n users for an item. We have an trained lightfm model, can we use the scores for a particular user and item using predict function and sort users based on that?

Start with the LightFM predict API and its documentation to determine whether scores can be computed for users against one item. The issue does not name a file, test, or acceptance criteria; done would require a decided approach and documented or tested support for retrieving the top users for an item.
