Where can I define the contact data to provide my users in case they want to report me failed attempts to access their service account while it was closed?

When there´s an attempt to access an account or operation that the user has closed with Latch, they get an alert on their Latch app. They have the option to dismiss it or to contact you through the contact data you can set up when you create an Application for your service in the My Applications section of the Latch Developer private area
