Add purchase note to order details in woocommerce

I would really appreciate some help.

I was looking for a way to display the purchase notes to the order details page, the only related topic I found was this , but it doesn’t appear to have solved the issue, and the code snippet inside doesn’t work.

And while we’re at it can I also add the product name to the order data metabox instead of having it in its own metabox ?

so what I want basically is displaying the purchase note and product name inside order date metabox, next to Billing, shipping, email address, etc.
