title: Delete content of Azure pipeline blob storage via Azure release
body: <p>I’m trying to build a CICD pipeline. I want to copy my new static React build bundle to Azure blob storage. As part of this, the old content needs to be deleted. The only action I seem able to take, however, is copy. Is it possible to do this?</p>
