I know that this is not possible, according to the documentation. But I found an application that can do this.

Answer 1

why is this not possible? The contact will not redirect tokens to third-party URLs only if permissions are requested to access the methods of the messages section . In other cases, there are no problems. response_type is better to use the value of token , less hassle.
if you need access to a user's wall then you need wall (Access to the wall) and offline (Access at any time)
permissions if you need access to the community wall then you need permissions groups (Access to groups) and offline (Access at any time)
