I want to create new role for my students to translate, but I dont have the section ROLES&PERMISSION so that I can create the new role for my students

I’m setting a new group of students that will be using RWS to translate. I’ve managed to create customer and as it is explained in the video teaching with RWS I have to create a new role so that my student will be able to translate and for that I have to click on ROLES & PERMISSION. The problem is that from my computer I don’t have this window. How can I do:?
