Gainsight oAuth flow

I am trying to setup the oAuth flow, by following what is described in the following documentation:

https://support.gainsight.com/Gainsight_NXT/01Onboarding_and_Implementation/Onboarding_for_Gainsight_NXT/Login_and_Permissions/OAuth_for_Gainsight_APIs#Create_Application

But the problem that I encountered is that there is no OAuth Applications tab available, when navigation to: /v1/ui/usermanagement#/authentication.

So the question is how do I create an oAuth app for which I could acquire the client id and client secret?
