Confusing docs: management group name vs. displayName vs. id

For Management Groups, Azure uses different property names in different locations.

| property name @Azure Portal | property name @ az cli | Example value |
| ------------- | ------------- | ------------- |
| Name | `displayName` | Production |
| ID | `name` | 628e99e2-3d07-4b2c-a8cb-725f277a0ed0 |
| - | `id` | /providers/Microsoft.Management/managementGroups/628e99e2-3d07-4b2c-a8cb-725f277a0ed0 |

Note that 'name' and 'id' mean different things in different places.

The docs for `az account management-group subscription add` say that the command has a required parameter `--name`, which is the "Name of the management group".

So which value is accepted? Is it the display name, is it the guid, or is either fine? (My tests show that it has to be the guid.)
Can you adjust the docs to clarify this?
