Certified Connector vs. App Source App for Power BI: Data Connector

I am trying to understand the best approach to offering a an out-of-the-box connector between Power BI desktop and Yext, to be used by other customers (i.e. not a custom connector that is limited to 1 account). The app will ONLY be a data connector and will NOT contain any visualization (i.e. not a template app).

I am unsure if this type of app can be offered in the App Source as a "Get it Now" app OR if it must be a Certified Connector for Power BI.

Any direction or distinction would be helpful for the logistics of the distribution of this!
