Problem with the blocker script?

Hello,
I am in the process of analyzing your plugin for its acquisition by a client.

In the free version, I find it difficult to understand the difference between “script blocker” and adding a script in “header script” in the category of a cookie.

I also tried to test the “wt_cli_plugin_integrations” filter that absolutely does not work in my theme’s functions.php file.

Despite reading the documentations I don’t know how to adjust your plugin if I add the Analytics tag in my functions.php file like this:

add_action( 'wp_head', 'script_ga' );
function script_ga() {?>
	<script async src="https://www.googletagmanager.com/gtag/js?id=UA-XXXXXX-1"></script>
	<script>
		window.dataLayer = window.dataLayer || [];
		function gtag() {
			dataLayer.push(arguments);
		}
		gtag('js', new Date());
		gtag('config', 'UA-XXXXXX-1');
	</script>
<?php }

Any help would be welcome
