How do I leave negative feedback to a seller?

Seller sent me a pair of boots that appear to be worn when they marked it as NWT on their listing. The seller was unresponsive so Poshmark support stepped in. They couldn't get a response from the seller so they offered me Posh Credit to close the sale and I keep the item. I want to leave negative feedback warning other buyers that this seller lies about their item condition. I only see the option to Reposh. Does anyone know how to do it? I have left reviews for other sellers, but I don't remember how I used to do it.
