To allow Video Producer to automatically start recording on the mac, you need to grant echo.app permission to use accessibility features.
The first time you try using Video Producer, you might receive this message on your Mac.
Please click "Open System Preferences", if you do not see this message or accidentally clicked Deny then please open System Preferences.
Now add echo to the Allowed Accessibility Apps, you can click the + sign to add echo, or drag echo into the box.
