Appeal deadline questions after an unemployment denial (update)

My claim was denied after 13 weeks of waiting, and the letter says I have a short window to appeal. There are 4 people counting on me, so I am trying to be careful. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

I printed my emails in order and wrote a one-page timeline. The hearing officer kept going back to it.
