If a subbot declares that it supports the v3 API in its /description endpoint, it will receive an extra key named jwt in its /start and /handle-event endpoints which can be used to authenticate this endpoint. In case the call to this endpoint fails because of an invalid or expired token, the subbot can not interact anymore with the user and the next message will trigger the Alcmeon scenario as usual.
