I want to just implement the OAuth provider config for dropbox sign. I actually have already done it.

Hey, we already have a provider for Dropbox.
Is there anything different you want to do?

Hey @bodinsamuel ! I was thinking of giving the Dropbox Sign integration a shot myself. Would it make sense to add it as a new provider?

Also, if there's another provider that’s getting more requests, happy to look into that one instead! Just let me know 🙌
