Denied unemployment, how do I appeal? after 11 years as an HR coordinator

My claim was denied after 23 weeks of waiting, and the letter says I have a short window to appeal. I am in Tampa, in case local advice matters. The letter lists a deadline and a hearing process, but it is hard to follow. Should I ask someone for free legal help?

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