SNAP after a layoff: what documents did you send? after 16 years as a web developer

I lost my job as a web developer and my household is applying for SNAP for the first time. I worked as a web developer before this. I have a final pay stub, a termination letter and my unemployment approval. What did you submit and how long did approval take?

Take photos of everything you send and write down the date. I had to resend one page and the record helped.
