You want to limit outgoing Owner notifications based on Team values within an Incident.
Out of the box, there is already a trigger for Owner Assigned.
Add a new conditional expression based on $(OwnerTeam == "Team1" || OwnerTeam == "Team2").
This will allow the trigger/quick action to only be run when those values are present for the Owner Team.
1. Launch Configure Application
2. Select Business Objects > Incident
3. Select Business Rules
4. Expand Triggered Actions
5. Edit the Owner Assigned trigger
6. In the Conditional Expression, add the following:
$(OwnerTeam == "Team1" || OwnerTeam == "Team2")
8. Enable the Trigger
9. Refresh browser
