Trying to identify a way to get the manager's name via WORKERS REST API within Alerts Composer.

Hello,

We are working to create new versions of our EMPS REST API-based alerts to a version using WORKERS REST API.

One field I cannot figure out how to pull within the alert is the manager's name. I know the manager assignment number is available but this is not of value for our alert recipients. I do realize that I can get the manager's name by running two separate calls via Postman (or your tool of choice), but this model does not seem that it will work within Alerts Composer.
