You are authoring a Bicep template to deploy a pooled host pool, its default desktop application group, and register that application group to an existing workspace in one deployment. Which property must you set on the application group resource to create the registration to the workspace?

To register an application group to an existing workspace in a Bicep template, you must set the properties.workspaceId property on the application group resource. This property takes the full Azure Resource Manager (ARM) ID of the target workspace, establishing the link between the application group and the workspace. properties.hostPoolArmPath is incorrect because it specifies the host pool associated with the application group, not the workspace. properties.registrationInfo is not a valid property for this purpose. properties.type set to "Desktop" defines the application group type, but doesn't register it to a workspace. properties.friendlyName set to the workspace name is a display name and has no functional impact on registration.
