Create Process Model using the Rename Users Smart Service

Question

Hi everyone, I was tasked with creating a process model to rename users using the rename users smart service. I only have the Start Node, the Rename Users node and End Node. I have multiple questions that I need answered that can hopefully help me get started as I am unable to find the guidance I need in documentation and other threads. Here are my questions: 
 
 What other nodes do I need/should I have? 
 When configuring the Rename Users Node what do I put for "Value" and "Save Into" for Inputs? 
 For the Rename Users Node how should I configure the Outputs? 
 
 I would also appreciate any other reference material you all might think is helpful. This is all I've found so far, and it wasn't enough to help me get started: Rename Users Smart Service - Appian 24.3

1) You can do away with just these 3 nodes, if you don't have to inform users of name change or update any DB. 
 2) you would need to add old and new names in value part of both the inputs 
 3) There is no output to confirm the success of smart service, so not mandatory to configure something on output part ---- One thing to check if this node can be run on basic user context or not. if not then run the node on context of "Who ever designed PM" option

Perhaps this might be helpful if you want to do a bulk rename.

1. These three nodes should be fine provided you have the list of names to be renamed, else you can have a script task to create the list. 
 2. Value should be the process variables that contains the old name and new name list, you can leave the saveInto as empty in this case 
 3. Input node is to pass the values of old and new names. You can leave output node untouched in this case
