Option join a tutorial using API call

[niels-beier]

It would be nice to be able to join a tutorial using an API call. Until now the only option is to join via the website which is inconvenient when nearly everything else can be managed completely using the API.

Yep, sounds like a great idea! 😄 I think you have to implement it yourself tho as I am unsure whether there is an official maintainer for müsli right now .. I do currently not have the time to contribute in my spare time. 😬

So how does Müsli actually add a student to a tutorial of a lecture? Till now, I was only able to find a test for adding a student to a lecture but the used webtest is not discoverable for me.
