Orchestrator not showing Task tab how to sove this problem?

I want to use Action Center into the Orchestrator.
I also tried some suggestions about Config file editing but also in my PC I didn’t find any Config file into C:\Program Files (x86)\UiPath\ this folder also.

Hi Pradeep,
To use UiPath action center you need to create an orchestration process. Some attended flow/ process that requires an action to be taken by a user in orchestrator.

This pic below shows how action center looks like in orchestrator.

Thank you.@ [shetanshudhar]
I already did part but in one you tube video i saw a Task tab in Orchestrator .
some web.config file configuration please tell me about that
