If you take a little time to read the dos and donts on Upwork, you will see that there are warnings of this sort of scam in several blogs and on the starter pages;
One of the ways of avoiding scams like this is to read the ToS, and then you would know that any communication with clients (with Upwork accounts) is against the rules and regs before a formal Upwork contract is in place. And Upwork or not, never agree to pay to get work
I very much hope you didn't do any of the stuff you agreed to in those screen shots.
Move on if you have - lesson learned. But do check the internet for freelancing advice and typical scams and also read all the help pages here.
