showColumn column names with spaces?

index.php?module=API&format=CSV&idSite=1&date=2022-11-06,2022-11-07&period=range&method=Live.getLastVisitsDetails&filter_offset=0&filter_limit=10&expanded=1&translateColumnNames=1&language=en&token_auth=[…]&showColumns=visitCount,visitDuration,url_(actionDetails_0)

For the API call above, I have three columns which I’m trying to receive “visitCount” “visitDuration” and “url (actionDetails 0)”. However I can’t figure out how to represent those spaces for the column to be found when you call the API. At this point, I’m just getting the first two columns.
