Android Question What is the right way to delete a file under a shared folder such as the DOWDLOAD folder on api 33?

Hi, everyone,
Since I only recently learned that Google has strictly changed the permission policy for reading and writing to external storage starting from a certain api version (Forgive me that my impression of Android internal and external storage is still stuck in a decade or so ago), I started to try to use SaveAs, ContentChooser, FileHandler, etc. introduced by Erel to deal with reading from and writing to files. (SaveAs - Let the user select a target folder + list of other related methods)

Now I basically have some concept about creating and reading files using these classes or libraries, but I still don't quite understand how to delete them under api33. Specifically, if my app creates a file in the DOWNLOAD directory, how should I delete it?

Thanks.
