"Request to share this app outside this account" is not working

Hello. I am trying to complete the " Request to share this app outside this account" but nothing happens when I click on “Request”. The app is " eTrainCenter OAuth Production". We really don’t need this to be on the marketplace and is currently embedded on our LMS. How do I make this request?

Hi @nrochford

When you submit this request, it will be evaluated by our team. Based on the information that you provided the request could be approved / denied.

Note that we only approve these requests for testing purposes for a short period of time. We expect that you publish the app once this request expires.
