TwitchWorks - The easy-to-use Twitch Integration for Unreal Engine 4!

Hi,
I am trying to make a demo, in which it shows login screen UI, in which user able to sign In with twitch authentication from its native android app,

  • I had login a twitch account and also registered my application .
  • I also have a locally server for back end use, in which by click on button it redirects to open twitch login screen.
    Question - How user return back after log In successfully in web browser and return back to its android app?
