Affected Resource(s)

Please list the resources as a list, for example:

• grafana_oncall_integration

If this issue appears to affect multiple resources, it may be an issue with Terraform's core, so please mention this.

resource "grafana_oncall_integration" "team_direct_paging" {
  provider = grafana.oncall_target

  name = "${var.name} oncall direct paging"
  type = "direct_paging"

  team_id = xxx.id
  default_route {
    slack {
      channel_id = xxx
      enabled    = true
    }
    escalation_chain_id = xxx.id
  }
}

Terraform Configuration Files

Expected Behavior

What should have happened?

Possibility to create and manage direct_paging for newly created teams

Actual Behavior

What actually happened?

Seems like during team creation there automatically created team direct paging.
However we need to manage by our-self direct paging and assign proper escalation policies.
Currently this not possible.
