commerce_digitalproduct.get_user_files snippet is used for listing digital products a user has previously accessed, as part of a "my account" section.
If the user is not logged in, they will be sent to the unauthorized page.
&tpl: the name of a twig template to use for rendering the digital products. Defaults to
digitalproduct/user_files.twig; you can either override that file in your twig theme or provide a different file entirely. The placeholders available in the template are the same as those on the thank you page and email templates; i.e. a root
digitalProductskey containing an array for each product, containing the different files associated with the product under all/files/resources keys.
