@JayChanggithub In case you want to send notifications from specific PD service into some Slack channels, brand new slack_connection resources might do the trick.

I've used this method and it does the job nicely, but have few drawbacks:

• you'll need to create some service account on PD side and pass his API key to PD provider config as user_token
• you'll need to link that PD service account with actual Slack user account (PD will perform requests to Slack API on behalf on that user)
• in case you want to send notifications into private channels that Slack user must be in that private channel (otherwise, notifications will not appear on Slack side)

In case you need extension add-on specifically, here is the code example which might work according to docs:

data "pagerduty_extension_schema" "slack_v2" {
  name = "Slack V2"
}

resource "pagerduty_extension" "slack"{
  name = "channel name"
  endpoint_url = "slack hook url"
  extension_schema = data.pagerduty_extension_schema.slack_v2.id
  extension_objects    = [pagerduty_service.promethues.id] 
}

However, multiple issues in that repo states that those Slack V2 extensions wouldn't work anymore due to changes on Slack API side and PD folks recommend using slack_connection instead (example).
