Appeal deadline questions after an unemployment denial after 14 years as a social media manager

My claim was denied after 6 weeks of waiting, and the letter says I have a short window to appeal. It has been weighing on me all week. The letter lists a deadline and a hearing process, but it is hard to follow. Did you bring documents or only talk?

Legal aid offices and some workforce centres help with unemployment hearings at no cost. A call is worth it.
