How do you create a view that removes fields and has types?

Looking at the documentation there is a way to modify the fields:

await RedactedUser.createCollection({
  viewOn: 'users', // Set `viewOn` to the collection name, **not** model name.
  pipeline: [
    {
      $set: {
        name: { $concat: [{ $substr: ['$name', 0, 3] }, '...'] },
        email: { $concat: [{ $substr: ['$email', 0, 3] }, '...'] }
      }
    }
  ]
});

But is there a way to remove the "name" and "email" fields? Using $unset doesn't seem to work.

Also is there a way to tie the schema for RedactedUser to an interface so that the name and email fields don't show up in autocomplete? Thank you!
