Bypass first level support for all tickets routed to a queue

Summary:

Hi all,

We need to set up a category/queue rule that only specific agents (belonging to a certain queue) from second level support can see whereas all agents from first level support cannot see.

The reason behind this choice is that the topic related to this category is quite sensitive.

We tried to set some rules but all failed and first level support agents can still view the SRs opened with this category.

Is there a way to achieve that?

Thank you,

Kind Regards

Silvia
