I have gotten an ornamental refusal. I understand it's an easy fix, but what exactly do I need to respond to the office action?

I've decided I want to respond to the office action by including evidence that proves that consumers associate the applied for mark with our company. Shouldn't be hard to do, our specimen was our company name on a sweatshirt in custom typography, but it is a logo that everyone associates with our brand. We also have used this same logo on our website and all social media. Can we use that? What exactly do we need to respond to this office action? Letters from consumers? Screenshots of our website with logo? Virtual advertisements with our logo? And I understand all specimens must be before the date we filed the trademark.
