Hello
I have a certain file type associated with my app. So that my app appears as a "open with" alterntive. However I would also like to get a notification if something of that file type gets deleted, so that my app can recognize/keep track of it. I think the iOS "Files" app does this, as it knows whether or not (any file in this case) gets deleted or gets added onto cloud apps. I would like to get notified for a special file type only.
As a side note I also wonder if the opposite would be possible, sending a notification to ("Files" app in this case), that a file of a particular has been deleted/ or to have an actual request to it to have it deleted. So that I in the aftermath of all this can use "Files" as my point of storage.
