I am struggling through the Canvas Dev and Friends course. I set up a server on localhost using Node.js and so far it works fine (albeit I have not figured out the activity 2: LTI Launch Authentication, but I will keep that for another question).
This question is about the LTI Activity 4: XML Configuration section . How to generate the XML Configuration file? I am trying to use the link here: https://www.edu-apps.org/build_xml.html with some bogus options, but I cannot copy the XML code! When I hover the text field I see a "forbidden" icon, see the screenshot below.
I found some other docs with examples, but they lack several tags and it is painful to guess from the course what is missing.
