Embedding a Google Drive folder in a workdoc using Embed everything widget

I would like to be able to embed a Google Drive folder in a Workdoc so that a user with access to the folder can navigate it as if they were in Google Drive (open and work with any file or subfolder under the root folder from within the WorkDoc, with permissions based on their access in Google Drive). When I add the folder link in the Embed everything widget, I get a 403 error stating “We’re sorry, but you do not have access to this page.” Is this a feature that might be available in the future?
