How to use Vendor Model with nRF Mesh


I have troubles using nRF Mesh with my Vendor model.

I have made a Vendor Model that should allow me to send messages through Mesh. Once my boards are provisionned, the app recognizes that I want to configure a Vendor Model and I feel like its mandatory to fill the Vendor Model Control. 

I just want to set the app key, the publish addr, and the subscription. Do I need to fill the Vendor Model Controls and if yes how ?

Thanks for your response,
