Using Azure AD B2C in Core NativeScript



I am trying to use Azure AD B2C to authenticate users.
I am following the steps mentioned in Azure AD B2C Documentation
Following these steps I was able to create a SignIn , SingUp policy and test it.
I am not able to find any documentation regarding how to use Azure AD B2C in NativeScript core.
There is a new Enterprise Auth Template but it is using Kinvey and Azure AD not AD B2C.
I am trying to integrate Core NativeScript(JS) and Azure B2C without Kinvey.
Was wondering if anyone has already tried this and can help me ?
