Why laravel livewire is not reseting the form?

This is my validation

<?php

namespace App\Livewire\Forms;

use App\Models\Contact;
use Livewire\Attributes\Validate;
use Livewire\Form;

class PostForm extends Form
{
    #[Validate(['required', 'string'])]
    public $name = null;

    #[Validate(['required', 'string', 'email'])]
    public $email = null;

    #[Validate(['required', 'string'])]
    public $phone_no = null;

    #[Validate(['required', 'string'])]
    public $subject = null;

    #[Validate(['required', 'string'])]
    public $message = null;

    public function store()
    {
        $this->validate();

        Contact::create($this->all());

        // Reset form fields
        $this->resetForm();
    }

    public function resetForm()
    {
        $this->reset(['name', 'email', 'phone_no', 'subject', 'message']);
    }
}

<?php

namespace App\Livewire;

use App\Livewire\Forms\PostForm;
use Livewire\Component;

class ContactForm extends Component
{
    public PostForm $form;

    public function save()
    {
        $this->validate();
        $this->form->store();

        // Reset form fields
        $this->form->resetForm();

        // Dispatch success message
        $this->dispatch('swal', [
            'title' => 'Message has been sent.',
            'icon' => 'success',
            'iconColor' => 'blue',
        ]);
    }

    public function render()
    {
        return view('livewire.contact-form');
    }
}
