EasyStore - Shipping Method Plugin Example

Hello,

my team and I are developing a shipping method plugin for EasyStore. We've read the documentation, but the link to download the example plugin is broken.
https://www.joomshaper.com/documentation/easystore/downloads/extension/easystore-custom-shipping-carrier-sample-plugin/1-easystore-custom-shipping-carrier-sample-plugin

Could you fix the link or send me the .zip file so we can use it as a reference for building our own?

Thanks, regards!
