Disfunctional package

[TheNewSound]

This package does not correctly implement the retrieval of a response code in the client side.
This has cost me a lot of missed form submissions!!!

You need to call grecaptcha.execute() upon form submission! not upon page load!
After two minutes the token will timeout.

Use this code instead of renderField() :

<input type="hidden" name="g-recaptcha-response" />
<script>
    (function() {
        document.getElementById('contact_form').addEventListener("submit", function(event) {
            event.preventDefault()
            grecaptcha.ready(() => {
                grecaptcha.execute('{{ config('googlerecaptchav3.site_key') }}', {action: 'contact_us'}).then((token) => {
                    event.target.querySelector('input[name="g-recaptcha-response"]').value=token
                    event.target.submit()
                })
            }, false)
        })
    })();
</script>
