Settings dialog of POWL Query adding new fields on hide/display columns SAP TM

Hello,

I need to add two more fields on the Hidden columns of a settings dialog on POWL query.Can anyone help me with detailed steps.Where do we find structure associated with this column. I referred the SAP TM guide where no information was provided on this. Please find the attached image(Overview road freight orders ->Open settings dialog) for reference.

Thanks in advance.
