Requesting permission in live app using test app

We have an app in live mode and to request user_friends permission we created a test app, pointed our app to the later and submitted the request for the live app.

When asking for help to a live agent in the request page about this procedure the instructions wre selecting your test app from App Review > Requests > Edit Request > Provide Verification Details. From the dropdown, select the test app. The problem is that there is no dropdwon?

Anyone happened this? How did you solved it?
