DTV Visa Thailand - Proof of work as a solo business owner/operator of a SaaS - Suggestions on what else to send?

DTV Proof Documents: Any SaaS (Software as a Service) owners or small biz owners applied for the DTV yet and had to provide extra proof of being eligible as a Digital Nomad? I have a small SaaS app that I am the owner and sole operator of, so hard to show them a "Portfolio" of work as a digital nomad, as I have a porfolio of 1 app :)

Any suggestions of other items to submit would be appreciated, I've sent them a bunch of extra documents such as statement and invoices to clients, so will see what they say about those.
