Azure serverless and Cosmodb

Hi,
I have to do some stuff with cosmodb from my functions.
How can i set the cosmodb connection ? inside the serverless.yml ?
I can’t find anything about that inside the documentation.
Can you help me ?

I found this page

But when i try Serverless plugin “cosmosDB” not found. Make sure it’s installed and listed in the “plugins” section of your serverless config file.
