Installing the Authorization Extension v2
One of the major changes between versions 1 and 2 of the Authorization Extension is the removal of the Applications section. This section was removed to simplify its inherent complexity, such as when it was used to define a policy for access control. The desired approach for such use cases is to use rules.
Upgrade the Extension Version
To upgrade the Authorization Extension, go to Extensions section of the dashboard and click Installed Extensions.
On the Authorization Extension row, you'll see a link that will begin the upgrade process to the latest version.
