Authorization Extension Doesn't show me a Token Contents section

I’m trying to get my SPA to call API and trying to follow the steps in the link below to configure the Authorization extension, but when I get to step 3 under Configure Extension where it says " This brings you to the Rule Configuration section of the Configuration page. All of the changes you make in the sections under Token Contents , such as those related to groups, roles, and permissions, will be reflected in the rule you export at the completion of this step." my Rule Configuration page does not have a Token Contents section.
