Giving access to user to use ewon cosy and flexy by giving message

Is it possible to give access to user to use ewon cosy and flexy by giving message from an authorised person?

Hello,

We do not have some type of messaging system to allow and disallow access. With a pro account Users and devices can be grouped up and admin can grant and revoke access as need. This can be utilized to control access.
