Direct messages access level with multiple users



I’m developing a nodejs app to retrive and analyze information of multiple twitter accounts. I granted authorization via passport-twitter and configured my app to have RWD permissons. I store the access token and token secret for every account in mongodb via mongoose. When I authorize every account I need, the sign in ask for access to direct messages, Then I try to get the “direct_messages” endpoint and could only retrieve direct messages from my personal account, any other account reponse “x-access-level” as read an write. Even in the “Test OAuth” button of my app settings I get the same acess level. How can I get RWD access level for multiple users in a single app?
