TWebHttpRequest and JWT

I am on my very first project here and have a REST server based on Delphi MVC that works with different debugging tools. AS I turn on the client side and invested in TMS WebCore I am a little puzzle with the very start, login in my server, saving the JWT and using it.

Could you please provide a clear sample on how to do this with the TWebHttpRequest, I am googled bored trying to get started

We have no experience here with Delphi MVC, so we cannot help on that part.
Wrt JWT, TMS XData also uses JWT, so maybe the doc for XData also helps for you when using Delphi MVC:
