Assign Mastery Profiles to a User. Assigning a Mastery Profile allows the User to exercise any activities within the profile during a Mastery Moment or Practice. User's will also have access to any Knowledge Cards associated with their Mastery Profiles. Multiple Mastery Profiles can be assigned with a single request by passing multiple Id's to the 'masteryProfileIds' array. To remove access and unassign a Mastery Profile from a User, refer to the Unassign Mastery Profile request.
