I see that the integration by default makes it easy to send alerts to teams in Opsgenie. I think that's not entirely correct since Opsgenie has the concept of a Service.
It's much cleaner to send a service monitor from Datadog to a service in Opsgenie which is covered by a team. Teams can in that way cover multiple services and move these around and this way it should also be easier to attribute alerts to a service.
Setting this up is not immediately obvious. Does somebody has a good guide for how to do this? I think it involves some setting or API key but the documentation on both sides is lacking.
