Some question

Hello i have same pre sale questions about https://villatheme.com/extensions/woocommerce-email-template-customizer/

1. Is it working with PHP 8.1?
2. Is it possible to use shortcode from 3rd plugins (ex. https://coderockz.com/downloads/woocommerce-delivery-date-time-wordpress-plugin/). I want to put code [woo_mb_order_meta-delivery_time] into a text message inside email (before i was using Woocommerce Email Drag and Drop Builder and it was possible).
3. Is it possible to use some conditional? For example different text for different order amount or shipping method or payment?

Thanks for information.
