Plugin to attached your Terms of Sales to the WooCommerce email

A while ago I did an explanatory tutorial on our WYCAN site to link a file ID uploaded in the media to a WooCommerce order status, however you had to tweak some code and not everyone is up to it. comfortable with it!

So I decided to make a plugin, very simple and which does the job, to allow you to select a file of your choice in the back office via the WordPress media, then to select an order status.
Once done, your file will be automatically sent to your customers based on the order status you have chosen.

This can be practical to attach your C.G.V for example (or any other document / file)
