Multible Views for a content-type

I'm looking for a way to find multiple views for a content type and I can't get any further.

A single view is not a problem

config.views = {
    ...config.views,
    contentTypesViews: {
      ...config.views.contentTypesViews,
      people: PeopleView,
    },
  };

But when I try to register an alternative view I get an error
I tried some Versions in the config.js like this:

config.views.contentTypesViews.people = {
   ...config.views.contentTypesViews.people,
     default: PeopleCardView,
        view: [
          {id: PeopleCardView, title: "Default View"},
          {id: PeopleView,  title: "Custom View"}
        ]
  };

or this:

config.views = {
    ...config.views,
    contentTypesViews: {
      ...config.views.contentTypesViews,
       people: {
        default: PeopleCardView,
        view: [
          {id: PeopleCardView, title: "Default View"},
          {id: PeopleView,  title: "Custom View"}
        ]
      },
    },
  };

The error message is

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object. Check the render method of View.
