Index constituents items in Data Item Browser (DIB)

Hello, I am trying to get some index constituents details of some indices using Eikon data API. I can get some basic data using "TR.IndexConstituentxxxx" items like the query below. However, I cannot find these fields using DIB in my Workspace. There is no item if I search using "TR.IndexConstituent". If I type "TR.IndexC", I got 3 items: "TR.IndexCalculationCurrency", "TR.IndexCloseTime" and "TR.IndexComparsonLevel". Why is that? Is it because my license is limited? But I can get the result using the query below. I want to know if the 4 items starts with "TR.IndexConstituent" are the only 4 available or there are more similar fields. How should I get a list for that?

df_constituents, err = ek.get_data(".HSI", ["TR.IndexConstituentRIC","TR.IndexConstituentName", "TR.IndexConstituentWeightPercent", "TR.IndexConstituentShares"],{'Sdate':'2023-09-26'})
