How to Export Selected Columns from Custom Script Report in ERPNext?

I have created a custom Script Report in ERPNext that shows employee check-in/check-out status. The report works fine and displays all columns properly. However, when I click the export button, I don’t get the option to select specific columns for export.

Report Type: Script Report

I want column selector to appear during export, where I can:

  1. Select/deselect specific columns
  2. Choose only required columns for export

How can I enable the native column selector for export in my custom Script Report? Is there a specific method or configuration I’m missing?
