Dusk: How to test root vue component?

I'm trying out Dusk's vue component assertions but from the docs I can't figure out how to reference the root component.

Say I have this method in my controller:

   public function show(User $user) : Response
    {
        return Inertia::render('User/Profile', [
            'user' => $user,
        ]);
    }

And therefore in my User/Profile.vue something like:

<script setup>

const props = defineProps({
    user: {
        type: Object,
        required: true
    },
});
///
</script>

In my Test say I want to test the correct data

->assertVue('user.name', 'Taylor', 'What goes here?');

How do I specify the selector for this 'root' component? Profile.vue in this case
