Dusk + Inertia + Vue 3, assertVue possible?

I'm starting a new app with laravel 12, inertia + vue, and trying to start doing tests

In my controller I have:

    public function index(Request $request)
    {
        return Inertia::render('Wizard/Index');
    }

My Wizard\Index.vue file is something like:

<script setup lang="ts">
import { ref, computed } from 'vue';
import { Head, useForm } from '@inertiajs/vue3';

const maxSteps = 6;
const form = useForm({
    lastname: '',
    firstname: '',
   (..... other things)
})
</script>
<template>
<div dusk="wizard-form">
(lots of things, inputs, buttons, etc)
</div>
</template>

my tests\Browser\WizardTest.php

<?php

use Laravel\Dusk\Browser;

test('the wizard works ok', function () {
    $this->browse(function (Browser $browser) {
        $browser->visitRoute('wizard.index')
                ->assertSee('Initial Steps')
                ->assertSee('Step 1 of 6')
                ->press('@start-button')
                ->assertSee('......')
                ->press('@continue-button')
                ->assertSee('Other Title')
                ->type('#lastname', "Doe")
                ->type('#firstname', 'John');
				// until this, it works OK and returns green
				// If I add any of the following ir does not run
				->assertVue('maxSteps', 6);
                ->assertVue('maxSteps', 6, '@wizard-form');
				->assertVue('form.lastname', 'Doe');
				->assertVue('form.lastname', 'Doe', '@wizard-form');
    });
});

the errors:

   FAILED  Tests\Browser\WizardTest > the wizard works ok                                                                                      JavascriptErrorException
  javascript error: Cannot read properties of undefined (reading 'setupState')

is there anything I'm missing? Do I have to use ANOTHER test suite (jest?) to test the inner workings of my components?
