There is a command group 'az_dt_endpoint_create'. This group of commands could 'add egress endpoints to 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_endpoint_create_eventhub'.The syntax is: az dt endpoint create eventhub --dt-name

                               [--resource-group]. The 1th example of the child command would be to use it to 'adds an eventhub endpoint to a target instance using key based auth', the syntax is: az dt endpoint create eventhub --endpoint-name {endpoint_name} --eventhub-resource-group {eventhub_resource_group} --eventhub-namespace {eventhub_namespace} --eventhub {eventhub_name} --eventhub-policy {eventhub_policy} -n {instance_name}. The 2th example of the child command would be to use it to 'adds an eventhub endpoint to a target instance using the system assigned identity for authentication', the syntax is: az dt endpoint create eventhub --endpoint-name {endpoint_name} --eventhub-resource-group {eventhub_resource_group} --eventhub-namespace {eventhub_namespace} --eventhub {eventhub_name} --mi-system-assigned -n {instance_name}. The 3th example of the child command would be to use it to 'adds an eventhub endpoint to a target instance using an user assigned identity for authentication', the syntax is: az dt endpoint create eventhub --endpoint-name {endpoint_name} --eventhub-resource-group {eventhub_resource_group} --eventhub-namespace {eventhub_namespace} --eventhub {eventhub_name} --mi-user-assigned {resource_id} -n {instance_name}. The parameter '--dt-name --dtn -n' is required. It is used to digital twins instance name.. The parameter '--eh --eventhub' is required. It is used to name of eventhub to integrate with.. The parameter '--ehn --eventhub-namespace' is required. It is used to eventhub namespace identifier.. The parameter '--en --endpoint-name' is required. It is used to endpoint name.. The parameter '--auth-type' is optional. endpoint authentication type.. The parameter '--deadletter-sas-uri --dsu' is optional. dead-letter storage container url with sas token for key based authentication.. The parameter '--deadletter-uri --du' is optional. dead-letter storage container url for identity based authentication.. The parameter '--ehg --eventhub-resource-group' is optional. name of eventhub resource group. if not provided, the digital twin instance resource group will be used.. The parameter '--ehp --eventhub-policy' is optional. eventhub policy to use for endpoint configuration. required when --auth-type is keybased.. The parameter '--ehs --eventhub-subscription' is optional. name or id of subscription where the endpoint resource exists. if no subscription is provided the default subscription is used.. The parameter '--mi-system-assigned --system' is optional. use the system-assigned managed identity for endpoint authentication.. The parameter '--mi-user-assigned --user' is optional. use an user-assigned managed identity for endpoint authentication. accepts the identity resource id.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--resource-group -g' is optional. digital twins instance resource group. you can configure the default group using `az configure --defaults group=<name>`..
