File Provider : unable to trigger `fetchPartialContents(for:version:request:minimalRange:aligningTo:options:completionHandler:)` when opening files

https://developer.apple.com/documentation/fileprovider/nsfileproviderpartialcontentfetching/3923718-fetchpartialcontents

fetchPartialContents(for:version:request:minimalRange:aligningTo:options:completionHandler:)

I need to use this function to fetch contents of the files partially. But it seems I'm just unable to receive any callback when i try to open the file via double click on finder.

I've tried to open files of different types and sizes but still i'm defaulting back to fetchContents(for:version:request:completionHandler:) .

I've been thinking if there are any specific configurations or requirements that i have to meet , so i could trigger this callback function for all the fetch Operations for files ?

If No, then where am i going wrong ?

Hi Guys, is there any updates about this issue ?
