Can I add my 'REST integration' to the Gorgias App store?

We have built a REST integration with Gorgias to support Texting over Gorgias. It's not an 'app' that is installed in Gorgias, but rather sets up webhooks, etc.

Can we list on the App store, or is it only for actual 'Gorgias Apps' that you install within Gorgias?

I've check the partner portal and I'm not sure how to list or create an app like this.

Thanks for the help!
