We did some tests
As Administrator: we took users from db of registered users and subscribe them in courses with different roles
As Manager: the same task doesn't show the role and the user is subscribed in the course with "no role"
In knowledge base, under manager role --> he "enables users assigned the role to access courses and modify them".
But this is not my case
Do you think it is possible to give to managers the power to decide what role to assign in courses to users?
