                          [--auth-mode {key, login}]
                          [--connection-string]
                          [--endpoint]
                          [--feature]
                          [--fields {conditions, description, key, label, last_modified, locked, name, state}]
                          [--key]
                          [--label]

                          [--top]. The 1th example of the child command would be to use it to 'list all feature flags', the syntax is: az appconfig feature list -n MyAppConfiguration. The 2th example of the child command would be to use it to 'list all feature flags with null labels', the syntax is: az appconfig feature list -n MyAppConfiguration --label \0. The 3th example of the child command would be to use it to 'list a specific feature for any label start with v1  using connection string', the syntax is: az appconfig feature list --feature color --connection-string Endpoint=https://contoso.azconfig.io;Id=xxx;Secret=xxx --label v1.*. The 4th example of the child command would be to use it to 'list all features with any labels and query only key  state and conditions', the syntax is: az appconfig feature list --connection-string Endpoint=https://contoso.azconfig.io;Id=xxx;Secret=xxx --fields key state conditions. The 5th example of the child command would be to use it to 'list 150 feature flags with any labels', the syntax is: az appconfig feature list --connection-string Endpoint=https://contoso.azconfig.io;Id=xxx;Secret=xxx  --top 150. The 6th example of the child command would be to use it to 'list feature flags with multiple labels', the syntax is: az appconfig feature list --label test,prod,\0 -n MyAppConfiguration. The 7th example of the child command would be to use it to 'list all features starting with  myapp1', the syntax is: az appconfig feature list -n MyAppConfiguration --key .appconfig.featureflag/MyApp1*. The parameter '--all' is optional. list all feature flags.. The parameter '--auth-mode' is optional. this parameter can be used for indicating how a data operation is to be authorized. if the auth mode is "key", provide connection string or store name and your account access keys will be retrieved for authorization. if the auth mode is "login", provide the store endpoint or store name and your "az login" credentials will be used for authorization. you can configure the default auth mode using `az configure --defaults appconfig_auth_mode=<auth_mode>`. for more information, see https://docs.microsoft.com/azure/azure-app-configuration/concept-enable-rbac.. The parameter '--connection-string' is optional. combination of access key and endpoint of app configuration. can be found using 'az appconfig credential list'. users can preset it using `az configure --defaults appconfig_connection_string=<connection_string>` or environment variable with the name azure_appconfig_connection_string.. The parameter '--endpoint' is optional. if auth mode is "login", provide endpoint url of the app configuration. the endpoint can be retrieved using "az appconfig show" command. you can configure the default endpoint using `az configure --defaults appconfig_endpoint=<endpoint>`.. The parameter '--feature' is optional. name of the feature to be listed. if the feature flag key is different from the default key, provide the `--key` argument instead. support star sign as filters, for instance * means all features and abc* means features with abc as prefix. comma separated features are not supported. please provide escaped string if your feature name contains comma.. The parameter '--fields' is optional. customize output fields for feature flags.. The parameter '--key' is optional. key of the feature flag. key must start with the ".appconfig.featureflag/" prefix. key cannot contain the "%" character. if both key and feature arguments are provided, only key will be used. support star sign as filters, for instance ".appconfig.featureflag/*" means all features and ".appconfig.featureflag/abc*" means features with abc as prefix. comma separated features are not supported. please provide escaped string if your feature name contains comma.. The parameter '--label' is optional. if no label specified, list all labels. support star sign as filters, for instance * means all labels and abc* means labels with abc as prefix. use '\0' for null label.. The parameter '--name -n' is optional. name of the app configuration. you can configure the default name using `az configure --defaults app_configuration_store=<name>`.. The parameter '--top -t' is optional. maximum number of items to return. must be a positive integer. default to 100..
