This is a basic
OkHttpClientinterceptor which takes aBehaviorRelayas an input parameter. On each outbound network request, the intercepter will use the latest token within the relay and attach it as an authentication header. This allows you to avoid having to add extra parameters toRetrofitmethod definitions 💪Found this in an old project of mine and going with this approach in Jarvis
