Hi,
we have an integration with Slack to get a message in Slack for critical alerts.

We have some heartbeat configurations with level P1-critical severity that we want to get a message in Slack when the heartbeat doesn't work.
But since we are talking about scheduled tasks in Windows Servers, most of our apps are not running at weekends, so we don't want to get a Slack message on weekends for these heartbeats.
As we see, Opsgenie doesn't support the option to configure these settings in integrations, only in Policies.
We tried to configure the Policy with tags to not create notifications on weekends:
But we do get notifications to Slack.
Any idea how we can stop sending the notifications to Slack?
