How can I give a containerRegistry to a DevcontainersCi task in an Azure DevOps YAML Pipeline, like in a Docker@2 task?

Currently pushing from this task fails, apparently due to missing authentication (understandable).

The property containerRegistry like in the Docker@2 task is not accepted by the DevcontainersCi task task.

Or is there another task which allows me to achieve the same, which is to also get the features from the devcontainer already included?
