# What this PR does
Semi-related to https://github.com/grafana/oncall-private/issues/2131
Addresses occasional task failures for
`apps.slack.tasks.update_slack_user_group_for_schedules` when trying to
update a Slack user group for a non-paid Slack account. [Slack's
documentation](https://slack.com/help/articles/212906697-Create-a-user-group)
mentions this is a paid only feature, hence the error
([logs](https://ops.grafana-ops.net/goto/-AWfsrrIR?orgId=1) from an
actual task):

Response: {'ok': False, 'error': 'paid_teams_only'}
```
Updated our docs on our Slack integration to emphasize that this feature
_only_ works for paid Slack accounts
