add_action( 'template_redirect', 'add_product_to_cart_conditionally' );

function add_product_to_cart_conditionally() { if ( is_admin() ) return; // Exit

// Below define the product Id to be added:
$product_A = 37; // <== For new customers that have not purchased a product before (and guests)
$product_B = 53; // <== For confirmed customers that have purchased a product before

$product_id = has_bought() ? $product_B : $product_A;

// If cart is empty
if( WC()->cart->is_empty() ) {
    WC()->cart->add_to_cart( $product_id ); // Add the product
}
// If cart is not empty
else {
    // Loop through cart items (check cart items)
    foreach ( WC()->cart->get_cart() as $item ) {
        // Check if the product is already in cart
        if ( $item['product_id'] == $product_id ) {
            return; // Exit if the product is in cart
        }
    }
    // The product is not in cart: We add it
    WC()->cart->add_to_cart( $product_id );
}
