MasterSlave send Notification to real customer

[Stefano2019]

Hello everybody,

I am using the MasterSlave module on version 6 of OTRS.
Everything works very well, except in this specific case which I now describe:

I create a master ticket, for example opened by me, and connect the various slave tickets to it.
When I send a notification on the master with the Reply, the notification is sent on the various Slave tickets but always to the customer of the master ticket.
So I get all notifications for every existing slave ticket.

I would like what is sent by the Master to be sent to the customers who have opened the slave tickets.

I hope I explained myself.

Thank you
