How to get legal employer name in the emps resource (Alerts Composer)?

Summary:

We have to use the emps resource to get a field from the Person Extra Information field. It is not available in the workers resource.

In the emps resource, we can see the LegalEntityId but not the name of the legal entity.

From POSTMAN, we can see a LegalEmployerLOV attribute/object and sending a GET request to it, it lists all the available legal employers, not just the legal employer for that employee. Upon trying to call that object in Alerts Composer, it says that it is a null object.

How can we get legal employer name for that specific employee when using the emps resource.
