PowerProtect DD: REST query "/rest/v3.0/dd-systems/{SYSTEM-ID}/mtrees" doesn't provide physical_capacity as documented

As per the REST API documentation, we should have an object for physical_capacity. But we cannot see that on DD OS v7.13. Is there a better query which can provide the physical_capacity of the MTree?
