Magento 2 – How to add data from a field in sales-order-item table to the order items in order confirmation email

I have a custom input field on each product item in the cart. The value is added to the sales-order-item table. The field is exposed to the order api as a custom attribute. I want to add the value of this field to each order item listed in the new order email that is sent to the customer. Can anyone suggest how to do this?
