I uploaded a plugin to discourse, and replaced in plugins/notebook-main/assets/javascripts/discourse/controllers/notebook.js.es6 , I replaced this file with the necessary interface file + I did the same with the hbs template.

Everything works in theory, except that we don’t want to save the changes.
