Currently, I don't see an option to use Teams in Process Author Business Rules. We are using Sugar v7.6 and will soon migrate to 7.8. I don't see the option to use teams in version 7.8 either.
We have certain workflows which revolves around teams, for example, "if a case is assigned to Team A -> Send an email to Team A"
But I couldn't create this rule in the Process Author workflow because Teams are not part of any criteria (in Business Rules or Process Definition)
