I'm currently assigned to create a Dropbox Extension.
This is a new feature that Dropbox released last November 2018, here's their article.
I read the Dropbox API documentation. I created a Business trial account (Advance). However, there was nothing about the submission/publishing of extensions.

So is this new feature only for companies chosen by Dropbox?
Will this ever be open to the public submissions/publishing?
Or maybe this is already open to the public and I'm just looking in the wrong places?
