delete method
Permanently deletes a file owned by the user without moving it to the trash.
If the file belongs to a shared drive, the user must be an organizer on
the parent folder. If the target is a folder, all descendants owned by the
user are also deleted.
Request parameters:
fileId - The ID of the file.
enforceSingleParent - Deprecated: If an item is not in a shared drive
and its last parent is deleted but the item itself is not, the item will
be placed under its owner's root.
supportsAllDrives - Whether the requesting application supports both My
Drives and shared drives.
supportsTeamDrives - Deprecated: Use supportsAllDrives instead.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
