Add a callback function to handle the token.

<script>
    function onSubmit(token) {
        document.getElementById("demo-form").submit();
    }
</script>

Add attributes to your html button.

<button
    class="g-recaptcha"
    data-sitekey="{{ config('recaptcha.key') }}"
    data-callback="onSubmit"
    data-action="submit"
>
    Submit
</button>

OR

Programmatically invoke the challenge

Use the <x-recaptcha::input /> in your form.

<form action="" method="post" id="recaptcha-form">
    @csrf
    <!-- Add for form inputs -->
    <x-recaptcha::input />
    <button type="submit">Submit</button>
</form>

Load the JavaScript with the recaptcha blade component before closing body tag.

<body>
    ...
    <x-recaptcha::script :formId="'recaptcha-form'" :action="'submit'" />
</body>
