I recently added comments to several work items where I mentioned various people on my team.  They only use the web ui.  I'd like to write a query they can use to see work items they are mentioned in.  I see a "Mentions" option in the query creator, but the only option is "exist" or "does not exist."  Is there a way to create a query that checks for mentions with a specific user id or to somehow leverage a feed in the web ui that will do the same thing?
