The 1th example of the child command would be to use it to 'update', the syntax is: az devcenter admin project-environment-type update --identity-type "UserAssigned" --user-assigned-identities "{"/subscriptions/00000000-0000-0000-0000-000000000000/resourcegroups/identityGroup/providers/Microsoft.ManagedIdentity/userAssignedIdentities/testidentity1":{}}" --deployment-target-id "/subscriptions/00000000-0000-0000-0000-000000000000" --status "Enabled" --user-role-assignments "{"e45e3m7c-176e-416a-b466-0c5ec8298f8a":{"roles":{"4cbf0b6c-e750-441c-98a7-10da8387e4d6":{}}}}" --tags CostCenter="RnD" --environment-type-name "DevTest" --project-name "ContosoProj" --resource-group "rg1". The parameter '--add' is optional. add an object to a list of objects by specifying a path and key value pairs.  example: --add property.listproperty <key=value, string or json string>.. The parameter '--deployment-target-id' is optional. id of a subscription that the environment type will be mapped to. the environment's resources will be deployed into this subscription.. The parameter '--display-name' is optional. the display name of the project environment type.. The parameter '--environment-type-name --name -n' is optional. the name of the environment type.. The parameter '--force-string' is optional. when using 'set' or 'add', preserve string literals instead of attempting to convert to json.. The parameter '--identity-type' is optional. type of managed service identity (where both systemassigned and userassigned types are allowed).. The parameter '--ids' is optional. one or more resource ids (space-delimited). it should be a complete resource id containing all information of 'resource id' arguments. you should provide either --ids or other 'resource id' arguments.. The parameter '--project --project-name' is optional. the name of the project. use `az configure -d project=<project_name>` to configure a default.. The parameter '--remove' is optional. remove a property or an element from a list.  example: --remove property.list <indextoremove> or --remove propertytoremove..

The parameter '--roles' is optional. a map of roles to assign to the environment creator.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--set' is optional. update an object by specifying a property path and value to set.  example: --set property1.property2=<value>.. The parameter '--status' is optional. defines whether this environment type can be used in this project.. The parameter '--subscription' is optional. name or id of subscription. you can configure the default subscription using `az account set -s name_or_id`.. The parameter '--tags' is optional. resource tags.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--user-assigned-identities -u' is optional. the set of user assigned identities associated with the resource. the userassignedidentities dictionary keys will be arm resource ids in the form: '/subscriptions/{subscriptionid}/resourcegroups/{resourcegroupname}/providers/microsoft.managedidentity/userassignedidentities/{identityname}. the dictionary values can be empty objects ({}) in requests.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--user-role-assignments' is optional. role assignments created on environment backing resources. this is a mapping from a user object id to an object of role definition ids.  support shorthand-syntax, json-file and yaml-file. try "??" to show more..
