The plugin does one thing and one thing only; prints the standard Google Tag Manager tacking script to the <code><head></code> of your website. To insert your container ID, navigate to Settings > General and then scroll to the bottom of the page.</p>
<h3>Composer</h3>
<pre><code>composer require claytoncollie/tracking-code-for-google-tag-manager

    /**
     * Set Google Tag Manager container ID.
     *
     * @param string $container_id Container ID.
     *
     * @return string
     */
    function ( $container_id ) {
