Runbook Step: Assign a Team
In addition to assigning specific roles you can also assign entire teams of people to an incident via Runbook automation.
The Runbook step has a single field to select which team should be assigned to this incident. This will pull in all the designated individuals on the team as well as assign them to any default roles, if configured.
Lastly, this will also automatically pull all of these people into the incident Slack channel.
Note: This requires you to have at least one team configured.
