allow Slack notifications work while using DisplayLink app on MacBook Air M1
This app and the Slack notifications wont work together. Using an M1 MacBook Air.
When one or more DisplayLink screens are active, please select the checkbox "Allow notification: When mirroring or sharing the display" in the "Notifications & Focus" panel in System Preferences
This should allow all notifications to display.
