Once I invoke kiteConnect.generateSession( .., .. ) I retrieve the user object and on inspecting its properties, I see the refreshToken attribute which always seems to be null.
Not sure if this property can be used to extend life of the accessToken.
1. Is it possible to renew accessToken without interactive user login ? if yes how ? 2. Whats the purpose of refreshToken since its always null. Under what circumstances can we assume it to have valid value ?
