Queue Routing Type

Option	Description
Parallel	All available agents are alerted at the same time. See prerequisite below.
Serial	Available agents are alerted one at a time, starting with the first agent on the list.
Round Robin	Available agents are alerted one at a time, equally distributed across all agents.
Longest Idle	Available agents are alerted one at a time, longest idle agent first to least longest idle.

If using Parallel routing, the below Teams PowerShell command is required to be ran for optimal agent experience:

Set-CsApplicationMeetingConfiguration -AllowRemoveParticipantAppIds @{Add="341e195c-b261-4b05-8ba5-dd4a89b1f3e7"}
