Issue Deploying Azure Premium Functions from CLI

So I create a function app using the following but I need a Premium function app to be created the below command doesn't create one for me .

> az functionapp create --resource-group test --os-type Linux --runtime python --name testar --plan test drift --storage-account xyzzy

Also When I use the Function app I created from the UI I am not able to push any functions to it , it does show pushed in local but I see nothing in the Azure Function Web page (Azure UI)

> sudo func azure functionapp publish test --build-native-deps

Please Let me know how to deploy Premium Linux Azure Function in python and How to push it to the app.
