# What this PR does
Removes unnecessary team checks enforced by public API, as they seem to
be outdated and not aligned with the web UI and docs.
From public
[docs](https://grafana.com/docs/oncall/latest/user-and-team-management/#manage-teams-in-grafana-oncall):
> Resources from different teams can be connected with one another. For
instance, you can create an integration in one team, set up multiple
routes for the integration, and utilize escalation chains from other
teams. Users, schedules, and outgoing webhooks from other teams can also
be included in the escalation chain.
