Granular Authorization in Process Visibility of workflow

[phalgunijain]

Hii All,

I want to place granular authorization in my process visibility of workflow For eg: For particular user or group of user is able to see only his set of the authorization in process visibility and not of other users

I am referring this blog Granular Authorization but its not covered with any of the steps or example.

Please provide any solution or steps how it can be achieved.

Thanks
