How to add Token Based Authentication to Jabbr?

[toandtc]

Hey guys,
I don't want to waste your precious time but I really need your help?
I want to add token based authentication to jabbr so that they can be use in android native and iOS native. (not Xamarin).
Suppose I have:

• An Authentication Server using .NET Identity 3.0
• A Chat Server using Jabbr
• A Client using Android Native or iOS Native.

Can you help me write example that get token from authentication server and use the token to access Chat Server.
Thanks you so much for your help
