cookie and analytics configuration

Good morning, everyone,
I have installed this plugin on my site but I am experiencing some issues.
I tried to enter a code for analytics via analytics and this is what comes up. i think the code entered is incorrect, but i could not find any other altrnative. I realized that the cookie does not work well especially in mobile view.

How can I fix this problem?

this is the code I put in the block script – thanks in advance

// Verifica se i cookie sono stati accettati dall'utente
if (cn_cookies_accepted()) {
// Codice di Google Analytics da eseguire quando i cookie sono accettati
// Sostituisci 'G-Y994P3MFHQ' con il tuo ID di tracciamento di Google Analytics

// Inserisci il codice di Google Analytics qui
(function (i, s, o, g, r, a, m) {
i['GoogleAnalyticsObject'] = r;
(i[r] =
i[r] ||
function () {
(i[r].q = i[r].q || []).push(arguments);
}),
(i[r].l = 1 * new Date());
(a = s.createElement(o)), (m = s.getElementsByTagName(o)[0]);
a.async = 1;
a.src = g;
m.parentNode.insertBefore(a, m);
})(
window,
document,
'script',
'https://www.google-analytics.com/analytics.js',
'ga'
);

ga('create', G-Y994P3MFHQ', 'auto');
ga('send', 'pageview');
}
