CSV from URL data source

Hi all! I don’t have CSV from URL data source on my self-hosted Redash? how can it be added? Also I tried using Google Sheets instead, but I try to choose a query error exists : It seems like we encountered an error. Try refreshing this page or contact your administrator.

See here:

The PR mentioned in that post has now been merged into the tip of master. I’m checking whether we can include it in the V10 release (currently in beta). Otherwise it will definitely be part of V11.

Could you explain in steps how I can implement these ones?
