Is there a possibility to read the contents of a work calendar with a known ID form a clientscript?

Hi, I am trying to find out whether it is possible to read the contents of a workcalendar from a V2 client script.

I was able to have a client script run at the Employee Record

I can find the ID of the work calendar from the context.currentRecord Employee.

I ran a search on the workcalendar with this ID in the following way:

// Retrieve the work calendar from the current Employee

        var calendarData = search.lookupFields({

            "type": "workcalendar",

            "id": 1,

            "columns": []

        });

But unfortunately the calendarData Array / object is empty. I know that the calendar with the internal ID of 1 exists.

I also looked in the record Browser - unfortunately it seems there is no documentation on the work calendar object at all.
