Don't display GA4 code to Google Lighthouse and Google PageSpeed

Google Analytics code removes one score from achieving a 100/100 score on PageSpeed Insights.

The solution with the Universal Analytics (UA) was to not show it to the google crawlers via:

if(navigator.userAgent.indexOf("Speed Insights") == -1 && navigator.userAgent.indexOf("Chrome-Lighthouse") == -1) {
    (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', 'UA-<PUT YOUR GOOGLE ANALYTICS ID HERE>', 'auto');
    ga('send', 'pageview');
}

Worked fine.

But as of today, UA is being deprecated and everyone needs to upgrade to Google Analytics 4 (GA4).

How can we use this code for GA4? So we don't display it to the appropriate Google crawlers.
