Retrieves a label with a specified name, or creates one if it doesn't exist.
Successful calls to this method always return a label, which can be specified in subsequent calls.
For example, in the Contacts API, Label Contact and Unlabel Contact calls will fail if you include a non-existent label. To ensure successful calls, you can call this method first, and then use the response in the Label Contact and Unlabel Contact calls.
To find an existing label without potentially creating a new one, call Get Label or Query Labels.
This function requires elevated permissions and runs only on the backend and on dashboard pages.
Display name to retrieve or create.
