                              --resource-group
                              --service

                              [--user-assigned]. The 1th example of the child command would be to use it to 'enable the system assigned identity', the syntax is: az spring app identity assign -n MyApp -s MyCluster -g MyResourceGroup --system-assigned. The 2th example of the child command would be to use it to 'enable the system assigned identity on an app with the  reader  role', the syntax is: az spring app identity assign -n MyApp -s MyCluster -g MyResourceGroup --system-assigned --role Reader --scope /subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/xxxxx/providers/Microsoft.KeyVault/vaults/xxxxx.
