Publishing a Box App OAuth 2.0 with JSON Web Tokens (Server Authentication)

We are building box integration within our SAAS portal and would like to use OAuth 2.0 with JSON Web Tokens (Server Authentication). This allows our users interact with their enterprise box account without the need to sign-in or authenticate individually.

Since our portal is a SAAS platform and we have multiple customers, how we can smoothen the process of retrieving the app configuration without asking each of our customers to create and authorize the app manually on their account.

I don't see a way to publish and distribute our integration app with Box App center when I use OAuth 2.0 with JSON Web Tokens (Server Authentication).
