How could you add percentile to a report relative to other respondents?

Hi! I'm looking at adding a percentile to a final score report relative to other respondents, something to the tune of "You scored 18 out of 30 points. Your score is in the 60th percentile relative to other respondents."
I tried looking up in Community questions if anyone had asked this before, but the only relevant question I could find was this one: https://www.qualtrics.com/community/discussion/5526/how-to-add-percentile-to-a-report
The answer given there was you need to export the scores and calculate that yourself, but how exactly do you do that? Is there any other way?
Sorry I'm a bit of newbie, so any help would be appreciated!
