Following the "LoopbackInterfaceRedirection" specification described in "RFC 8252 OAuth 2.0 for Native Apps", I would like to configure Box to receive the authentication code on an unused free port on Windows and send it to the Box custom app configuration screen (https://app .box.).
However, it is not possible to specify a dynamic port for the "OAuth 2.0 Redirect URI" in the Box custom app configuration screen (developers/console/app/xxxx/configuration).
I would like you to specify the dynamic port as per the specification of "LoopbackInterfaceRedirection" described in "RFC 8252 OAuth 2.0 for Native Apps".
