Variable product button and price range

Hello Guys!

I have a problem, with “select option” button (Woocommerce).

I have 3pcs variable product, and I used this snippet to change “select option” button text.:

// Change button text on WooCommerce Shop pages
add_filter( 'woocommerce_product_add_to_cart_text', 'woocustomizer_edit_shop_button_text' );

function woocustomizer_edit_shop_button_text() {
    global $product;
    $product_type = $product->get_type(); // Get the Product Type
	
    // Change text depending on Product type
    switch ( $product_type ) {
        case "variable":
            return __( 'Megnézem!', 'woocommerce' );
            break;
        case "grouped":
            return __( 'Megnézem!', 'woocommerce' );
            break;
        case "external":
            // Button label is added when editing the product
            return esc_html( $product->get_button_text() );
            break;
        default:
            return __( 'Megnézem!', 'woocommerce' );
    }
}

As you see in this picture, the variable products have not price in the admin, only If I open them… https://ibb.co/XDKHPxv

How can I solve this problem, and how can I change the “select options” button!? ??
I tried the “Woocommerce costumizer” plugin ….but its not helped ??

I would like to see this: https://ibb.co/wWwYYGP
I dont know how can I set this, to show product price range everywhere in my site.
And of course change the “select options” button text also important ! ??

Can you give me any advice?
Thank you
