Deleted Tickets in Zoho desk

Deleted Tickets in Zoho desk

Dear Zoho,

Can an agent be disabled from deleting a ticket?

As of now the agent is assigned with a role of "Tickets allotted to him and unassigned tickets". Now the agent can detete the tickets, but how can we know if a ticket is deleted and even cleared from recycle bin.

What should be the control Check for this issue?
