As I understand it, we start a quiz-taking session by POST to submissions: https://canvas.instructure.com/doc/api/quiz_submissions.html#method.quizzes/quiz_submissions_api.create.
Is there a way to start a quiz taking session on behalf of a user without that user needing to login? For example, if our course is connected to an LTI tool that presents the questions to users in a separate UI, can we create the quiz submission without needing the users bearer token?
