   DeleteUserOptions specifies a collection of one or more `user_ids` to be deleted.
 
-  `user` soft|hard determines if the user needs to be hard- or soft-deleted, where hard-delete
-  implies that all related objects (messages, flags, etc) will be hard-deleted as well.
-  `conversations` soft|hard will delete any 1to1 channels that the user was a member of.
-  `messages` soft-hard will delete any messages that the user has sent.
-  `new_channel_owner_id` any channels owned by the hard-deleted user will be transferred to this user ID
+  `user`:
+    - soft: marks user as deleted and retains all user data 
+    - pruning: marks user as deleted and nullifies user information 
+    - hard: deletes user completely - this requires hard option for messages and conversation as well
+  `conversations`:
+    - soft: marks all conversation channels as deleted (same effect as Delete Channels with 'hard' option disabled)
+    - hard: deletes channel and all its data completely including messages (same effect as Delete Channels with 'hard' option enabled)
+  `messages`:
+    - soft: marks all user messages as deleted without removing any related message data
+    - pruning: marks all user messages as deleted, nullifies message information and removes some message data such as reactions and flags
+    - hard: deletes messages completely with all related information
+  `new_channel_owner_id`: any channels owned by the hard-deleted user will be transferred to this user ID
