                                        --key-type
                                        --namespace

The 1th example of the child command would be to use it to 'set the key that all apps in an appservice plan use to connect to the hybrid connections in that appservice plan', the syntax is: az appservice hybrid-connection set-key -g MyResourceGroup --plan MyAppServicePlan --namespace [HybridConectionNamespace] --hybrid-connection [HybridConnectionName] --key-type ["primary"/"secondary"]. The parameter '--hybrid-connection' is required. It is used to hybrid connection name.. The parameter '--key-type' is required. It is used to which key (primary or secondary) should be used.. The parameter '--namespace' is required. It is used to hybrid connection namespace.. The parameter '--plan' is required. It is used to appservice plan..
