Authenticated users cannot use the module.

Problem/Motivation

While the module does work for user 1 the module doesn't work for regular authenticated users, right now. It seems there is a permission required that doesn't exist.

Steps to reproduce

Install Prismjs module
Enable button and filter in /admin/config/content/formats/manage/basic_html?destination=/admin/config/content/formats
save the form
enable the forum module as well
create a forum topic as user 1 or admin and add some examples in the body useing the prism js button
save the content
create a regular authenticated user
make sure that authenticated users have permission to write comments
log in as authenticated user not user 1
create a comment for your forum topic
click the prism button

result: The JS console shows {"message":"The \u0027use text format advanced\u0027 permission is required."} while the statuscode of /prism-js/dialog?_wrapper_format=drupal_modal is 403

So currently there is no chance usual users can use prism.
