You need to configure OmniChannel to route correctly.

Box 1: Two

You must create two types of Omnichannel queues: regular and escalated.

Box 2: Add a routing rule for a push on owner assignment in Omnichannel

Tickets assigned to a representative must be automatically placed in that representative's queue.

A customer initiates a conversation from the portal, and the conversation reaches the Omnichannel system. Now, based on the routing rules condition defined in the routing system, it starts routing the conversation to the appropriate queues.

When the conversation reaches to the queues, the work assignment system assigns the conversation based on triggers.
