I'm following the https://community.d2l.com/brightspace/kb/articles/1529-adding-course-content using Postman. I've followed most of the tutorials on the site with success with this one exception. When I run the API call, according to the directions, I get a { Errors: [ {Message: "Insufficient scope to call API.Required: content:modules:read"} ] }. How can fix this?
