Revert the flows/get back the out of box flows to normal

[sathwikc]

Hi experts,
I have modified a flow name: "service catalog item request",
which has a subflow: "Requested Item Manager Approval", 
I have changed the action "Ask for approval", which has a rule: approve "input<requested item<requested for<manager".
Now I can't revert it back nor find a data pill of "requested for".
This is out of box flow which servicenow gave as a default flow.
Is there any chance to revert this out of box flow, like repair any plugins, I have done it in my PDI, or by chance can I export and do import?
I was doing this for ITSM implementation lab activities, Lab: 4.4.1 Create a dynamic flow.

Hi @sathwikc ,
Copy flow sys_id

Then in navigator write sys_update_version.LIST

paste sysid in name column like with contains * like this

From here you can revert to older version

I have tried later, but I couldn't find the correct sysID and update sets, so I have decided to make a new flow similar to the out of box
while I was creating a new I have found that there is no data named "requested for" in the flow
I have created a random new flow named TST but I can't find the "requested for" data
