Duplicate Slack notifications for assigned team members

[TBakes]

Describe the bug We use github notifications and love them. When someone's review is requested, they get a Slack message. When a team they're on is requested, they get a notification. But, we recently tried out the Enable auto assignment feature within the team, and had some troubles. When a team is assigned, everyone on the team gets notified, THEN the individual who is selected via round-robin gets another notification. We hoped/expected for github to figure out which team member to assign, and then send a slack notification to just that team member, instead of the whole team.

Even if you enable Only notify requested team members, you don't get notification via GitHub notification inbox but slack app. https://docs.github.com/en/organizations/organizing-members-into-teams/managing-code-review-settings-for-your-team#configuring-team-notifications

Despite the above-mentioned setting being applied, team members are still getting notified twice via the Slack integration when automatic assignment is enabled. Is there a setting or filter I'm missing?
