Can anyone tell me please what this checkbox will do?
Use Pagerduty teams?
If you choose to select this checkbox, when automatically provisioning Assignment Groups into PagerDuty, a PagerDuty Team will also be created, and the members in the assignment group will be automatically added to the PagerDuty team.
For more information about this feature and other features available in v5 of the ServiceNow integration, you can visit this What’s New community post.
I hope this helps!
