There is a command group 'az_dt_identity'. This group of commands could 'manage identites of a digital twins instance'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_dt_identity_remove'.The syntax is: az dt identity remove --dt-name
                      [--mi-system-assigned {false, true}]
                      [--mi-user-assigned]
                      [--resource-group]. The 1th example of the child command would be to use it to 'remove the system assigned identity from a digital twins instance', the syntax is: az dt identity remove -n {instance_name} --mi-system-assigned. The 2th example of the child command would be to use it to 'remove two user assigned identities from a digital twins instance', the syntax is: az dt identity remove -n {instance_name} --mi-user-assigned {resource_id} {resource_id}. The 3th example of the child command would be to use it to 'remove all identities from a digital twins instance', the syntax is: az dt identity remove -n {instance_name} --mi-user-assigned --mi-system-assigned. The parameter '--dt-name --dtn -n' is required. It is used to digital twins instance name.. The parameter '--mi-system-assigned --system' is optional. remove the system-assigned managed identity to this digital twin instance.. The parameter '--mi-user-assigned --user' is optional. remove user-assigned managed identities to this digital twin instance. accepts space-separated list of identity resource ids.. The parameter '--resource-group -g' is optional. digital twins instance resource group. you can configure the default group using `az configure --defaults group=<name>`..
