Hello,
thanks for this code... In my case, I think it can be a good solution for my users also.
However, it doesn't work for me. I have follow your instructions (head in additionnal HTML, replacing the url with my site in the code).
The new button is here but I have a 404 error when I click it (The requested URL was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.).
I've tried few solutions but unfortunately, I don't really know how codes work.
Maybe, you can have a solution ?
Thanks in advance and sorry for my english (I'm french, as my site that is a moodle 3.9.2+ with lambda theme).
