I can do an export based on my filter (risk score) but the export is not showing me the uses who are using the apps. How can i get the users exported ?
If you click on the name of the discovered app, it will take you to the app overview page. There, you should find a "Cloud app usage" link that will take you to the usage overview, which has yet another set of links to see the usage breakdown by users or IPs or devices, depending on what info is in the source data. If you click on "Users", you will see the list of users with an export option.
