How to infer variables from multiple requests?

That’s a great app! I switched here from Insomnia, but I didn’t find a solution to infer variables from multiple requests like this plugin does:

For instance: I have a signup and a signin requests, And if I do signup i want to to get token from signup, if i do signin then from signin, and also i have a request called tokens which can refresh current token, how i can do it? I’ve read your post about response function, but didn’t find anything that can be helpful to my situation.
