I'd like to know whether it's possible or not for a manager/team leader/senior to reply to customer on his ticket via the web interface ? Of course, the ticket is already owned by an agent.
I don't to change owner to the senior just for one answer.
The goal is just to bring some expertise knowledge to the agent/customer by sending/requesting more information within the ticket.
I hope I'm clear enough

Thank you in advance for your help.
