If someone requests approval for an email and the approver has the Slack integration it would make sense to send that approval request in Slack. Currently, comments with an @mention will go to the recipient in Slack but not approvals in general. The notification configuration doesn't include the new approval feature as an option.
My boss uses Slack noticifations for Hubspot and the one thing missing is that approvals feature and alerts being sent to Slack when those are requested of a user.
