How to change the separator in CSV export?

Hi all,

We are looking for a way to change the default delimiter in CSV export from a widget from ',' to ';'. We have seen this entry (https://support.sisense.com/kb/en/article/excel-export-changing-the-delimiter) but it didn't work.  

I have reviewed the configuration settings, but I'm unable to locate how to achieve that. 

Any idea?

Thanks
