Restrict user access to certain notebook instances

To restrict access for certain users to specific Braket notebook instances, you can add a deny permissions policy to a specific role, user, or group.

The following example uses policy variables to efficiently restrict permissions to start, stop, and access specific notebook instances in the AWS account 123456789012, which is named according to the user who should have access (for example, user Alice would have access to a notebook instance named amazon-braket-Alice).
