How to add Google Ads conversion purchase event to my WooCommerce Thank you Page

I saw this
Adding Google Ads Event Snippet To Conversion Page (thank you.php)

But I have a different situation. I am using ” Auto Complete Processing WooCommerce orders on Thank you Page” and “Redirect WooCommerce checkout page” all these are inside my functions.php file.

This is what my functions.php file looks like. I hid my site with ” ********* “

//Auto Complete Processing WooCommerce orders on Thankyou Page

add_action( 'woocommerce_thankyou', 'custom_woocommerce_auto_complete_order' );
function custom_woocommerce_auto_complete_order( $order_id ) { 
    if ( ! $order_id ) {
        return;
    }

    $order = wc_get_order( $order_id );
    if ( $order->has_status('processing') ) {
        $order->update_status( 'completed' );
    }
   
}

// Redirect WooCommerce checkout page to ******************** after the payament
add_action( 'woocommerce_thankyou', 'pfwp_redirect_woo_checkout');
function pfwp_redirect_woo_checkout( $order_id ){
    $order = wc_get_order( $order_id );
    $url = 'https://*********/*********/*********/';
    if ( ! $order->has_status( 'failed' ) ) {
        wp_safe_redirect( $url );
        exit;
    }
}

And I want to add the Event snippet inside the Thank You for google ads.

<!-- Event snippet for Purchase conversion page -->
<script>
  gtag('event', 'conversion', {
      'send_to': 'AW-***********/********kDENy8vL4o',
      'value': 1.0,
      'currency': 'SAR',
      'transaction_id': ''
  });
</script>
<!-- End Event snippet for Purchase conversion page -->

Because I am redirecting the thank you page to another page, the script will trigger? Or not?

And how and where do I add the Event snippet at the functions.php because I have a lot of code that control WooCommerce?
