-     - `appgw.resourceGroup`: Name of the Azure Resource Group in which App Gateway was created. Example: `app-gw-resource-group`

    ```bash
    az identity show -g <resource-group> -n <identity-name>

-   `<resource-group>` in the command above is the resource group of your App Gateway. `<identity-name>` is the name of the created identity. All identities for a given subscription can be listed using: `az identity list`
