Woocommerce country based pricing

Question

I want to show different price for different countries. The pricing rule will be like (regular_price + 1)*conversion_rate. Now I am using this snippet but it's not showing the price anywhere. I echo it but it only showing beside the cart button.

add_filter('woocommerce_get_price', 'adjust_price_for_gcc', 10, 2);

function adjust_price_for_gcc($price, $product) {
    $location = WC_Geolocation::geolocate_ip();
    $gcc_countries = ['BH', 'BD', 'OM', 'QA', 'SA', 'AE']; // GCC country codes

    if (in_array($location['country'], $gcc_countries)) {
        $price = $price + 1; // Increase price by 1 for GCC customers
    }
    echo $price;
    return $price;
}

please help. I am new to wordpress development.
